Eco-Travel in Colorado: Boulder, Fort Collins, Estes Park and Pawnee Grasslands

This just in - Colorado has mountains!

OK, it's not exactly the newsflash of the century, but I'm sure I'm not the only person who ever flew into Denver (where I'd spent my entire previous trip to Colorado) and wondered whether the distant outline on the horizon was in fact the Rocky Mountain range.

Well, after spending a week in northern Colorado bouncing around between Boulder, Fort Collins, Estes Park and the Rocky Mountain National Park, I can in fact report that the mountains do exist.

(Although truth be told they look remarkably similar up close to the fake mountains at the Disney theme parks, especially the Big Thunder Mountain ride. I kept expecting a theme park coaster full of screaming kids to materialize from behind an escarpment at any moment. Nonetheless, despite the resemblance, I'm prepared to believe that the Rocky Mountains are not just a creation of Uncle Walt.)

And now, with apologies for such extensive throat clearing, I present a few nuggets (pun intended) of information on eco travel in northern Colorado.

Boulder - The Denver Post has described Boulder as a "little town nestled between the mountains and reality."

It's true. Boulder is very close to the mountains - and it is a bit separate from reality. There's a certain vibe here as though the 60's never ended. Strolling around the pedestrian-only Pearl Street Mall on a Thursday afternoon, my wife and I encountered a sizeable crowd sitting in the shade and listening to a duo of folk singers. I don't think I had smelled so much incense in the air since graduating college.

Later that night, in the courtyard of the sophisticated yet comfortable St. Julien Hotel & Spa, a much larger crowd rocked out in unpretentious glee to the upbeat sounds of a Brazilian band, while women and children hula-hooped on a grassy lawn.

Here's the best way I can sum up my experience in Boulder. When the valet at the St. Julien found out I was writing a story on the place, he told me how much he loved the town for its "gentle" vibe. I've never heard anyone else describe their town as gentle, but it really does seem to fit Boulder.

Anyway, back to the St. Julien. With its in-room recycling bins, its use of low-VOC materials (carpets, paints and wall coverings), its use of earth-friendly cleaning products and its decision to avoid any leather products, the St. Julien has a long list of eco-friendly qualities. The hotel's restaurant - Jill's - not only serves a seriously delicious buffet lunch (salads, pizzas, sandwiches, soup, fresh bread, etc.), it does so while sourcing as much organic produce and humanely-farmed livestock as possible, composting its food waste and recycling its cooking oil for the creation of biodiesel. The hotel recently planted an on-property herb garden to make sure Jill's had plenty of locally-grown ingredients for its recipes. Some of these same herbs are then incorporated into the St. Julien's spa treatments. Expect to pay approximately $240-260/night for a room at the St. Julien this fall.

We took advantage of another eco-friendly perk at the St. Julien -- free use of cruiser bikes for hotel guests. The cheery bikes look cute and retro, but the lack of hand brakes may frustrate some riders. That grumble aside, the hotel is practically across the street from an entrance to one of Boulder's nicest bike paths that threads alongside Boulder Creek.

The St. Julien also sits close by the Chautauqua Park area, part of more than 45,000 acres of open space land owned by the city of Boulder and managed by the department of Open Space and Mountain Parks. The Chautauqua area is not only convenient to downtown, it contains a variety of trails leading right up to the famous Flatirons rock formations that serve as beautiful backdrop to the town.

You'll frequently see Boulder appear at the top of city lists for its livability and healthy environment. For example, the town attracts a wealth of athletes who come to train in its sunny, high-altitude environment. But it's the community that really makes Boulder special. The city is proud of its claim to be the first city in the U.S. to tax itself for the acquisition, management and maintenance of open space back in 1967. The city's residential green building code dates to 1996 - another first.

That community has attracted the type of people who own Green companies including Namasté SolarIZZE sparkling juicePangea Organics (previously reviewed on 1GreenProduct.com), Horizon OrganicFiona's Granola and Ellie's Eco Home Store.

The city is considered to be a fine-dining destination. We didn't spend enough time in town to confirm or deny that reputation, but I will say that chef Eric Skokan's Black Cat Farm Table Bistro cooks up some awesome organic and local dishes. I was particularly impressed with the beet salad (sliced paper thin) and the cucumber soup (refreshing and clarifying on a warm evening). Service was warm, friendly and informal - par for the course in Boulder.

In short, it's a bit silly trying to describe everything that's eco about Boulder. Let's just say that Green-minded folks will breathe deeply of the clean mountain air and feel instantly at home. For plenty more Green info on Boulder, visit the Environment page of the Boulder CVB.

Fort Collins - This college town (home to Colorado State University) has a great reputation. Among the many awards won by the city, residents seem fairly proud of the  2006 designation by Money Magazine, which called Fort Collins the best place to live in the U.S.A.

More recently, the Natural Resources Defense Council placed Fort Collins #3 on a list of 'Smarter Cities' based on environmental standards including use of renewable energy, creation of green space, encouragement of alternative transportation and energy-efficient building techniques.

Speaking of alternative transportation, the 280+ miles of bike lanes and 30+ miles of bike paths have helped Fort Collins achieve a Gold level designation as a Bicycle Friendly Community. Recently, the city installed new bike racks downtown with the help of New Belgium Brewery, a local institution praised as much for its eco-sensibility as for its awesome microbrews.

Visitors to Fort Collins can take a tour (and tasting) at New Belgium, learning why the brewery's signature beer is called Fat Tire and about the important role bikes play in the company's culture.

I have a lot of respect for companies and communities that are willing to put their money on the line alongside their Green sensibilities. Just as the citizens of Boulder took a hit to their pocketbooks when they voted to tax themselves to preserve Green space, so too did New Belgium's employees take an economically irrational decision back in 1999 when they voted unanimously to give up profit-sharing bonuses for 10 years in order to pay a premium for wind-powered electricity.

New Belgium also has a sweet policy of giving employees a free cruiser bike on their one-year anniversary with the company.

Meanwhile, the company isn't slowing down on its efforts to become Greener by diverting more waste from landfills and planning installation of a solar photovoltaic array. Basically, I came away super-impressed by New Belgium's ability to turn challenges into beautiful eco-friendly solutions. Faced with the destruction of the state's beautiful lodgepole pine forests by beetle infestation, New Belgium decided to use some of the fallen dead trees to build its new packaging hall. When the company had to find a better way to treat wastewater from its brewing and packaging activities, it built its own treatment facility that captured methane gas and used it to power a co-gen plant that supplies up to 15% of the company's electrical needs.

And did I mention that the beer is pretty tasty? ;-)

Incidentally, Fort Collins also has other well-regarded microbreweries (Odell Brewing CompanyFort Collins Brewery and Coopersmith)  and a massive Anheuser-Busch macrobrewery.

Fort Collins also has an ambitious project underway to create the world's largest zero-energy district. Called FortZED, this district encompasses the historic downtown and the main campus of CSU, aiming to reduce energy demand and simultaneously meet the remaining demand with Smart Grid technologies including wind and solar energy.

Colorado State University also plays a major role in Green research and development. The university's Engines and Energy Conversion Laboratory (EECL) looks for ways to make engines more efficient and investigates potentially useful biofuels like algae. If you happen to be visiting Fort Collins with a group of at least 7 other eco-minded friends, you may be able to organize a tour of EECL by contacting Stacy Grant at CSU.

While in Fort Collins, eco-minded visitors might like to sample the yummy organic/vegan fare at Tasty Harmony. I enjoyed the jackfruit taco and the awesome berry smoothie.

If you're looking for a little adventure, Mountain Whitewater Descents offers rafting trips on the Cache la Poudre river, Colorado's only Wild and Scenic River. I'd been rafting once before and had unintentionally gone swimming a couple of times on that previous trip, so I was a little anxious about the ride, but the Cache la Poudre trip actually turned out to be just the right mix of relaxing floating and adrenaline-pumping rapids. MWD's prices range from $49 to $109 per person for half-day or full-day rafting trips. (Since the rafts are human-powered and go downstream with the current, the experience seems relatively benign and eco-friendly for the river. Of course, there are diesel-powered buses involved in bringing the rafts and people upstream to the put-in point, so the experience can't be classified as totally eco-friendly, but MWD does give back to the environment with an annual river cleanup, tree-planting to offset carbon emissions, purchases of wind-power credits (with a goal of being 100% wind-powered) and donations of 2% of gross receipts to non-profit organizations. The company also lives the recycling credo in its everyday life by re-using salvaged lumber and materials in its office and recreation areas.

If you'd rather park your car and spend your time walking and biking around Fort Collins, I'd suggest staying at the Armstrong Hotel, a 1923 landmark that was restored in 2004. With free wi-fi in every room, a great location and free cruiser bikes available to guests, the Armstrong was a great home base while in Fort Collins. Cat lovers take note -- lazy kitty Oreo seems to spend all day snoozing away in the chair next to the front desk and is perfectly happy to be petted whenever you like.

If you want to get out of town and enjoy nature, the city of Fort Collins does have a Natural Areas Program funded by citizen-initiated taxes and encompasing more than 32,000 acres of land suitable for hiking, biking, bird watching and horseback riding - most of which are open from early in the morning (5 a.m.) until late at night (11 p.m.).

Two other quick eco tidbits about Fort Collins. The city has a Climate Wise program to help businesses figure out ways to reduce waste, save energy, conserve water and promote alternative transportation. And in case you're not staying at the Armstrong, there's also a local Bike Library in Fort Collins where you can borrow a bike for up to 7 days at no cost.

Oh and in case you're in the market for a lithium-ion powered tricycle, I just read about a new electric bike shop called RunAbout Cycles that relocated to Fort Collins.

Estes Park - Estes Park is one of the gateway towns for Rocky Mountain National Park, which gives eco-minded travelers more than a quarter million acres of rugged land with almost 360 miles of trails, 150 lakes and more streams, vistas and wildlife than you can shake a stick at.

If you're looking for non-motorized ways of exploring the beautiful countryside around Estes Park, consider a horseback ride from Aspen Lodge or an exhilirating downhill bicycle tour with Colorado Bicycling Adventures.

(Be sure to wear warm clothes on the cycling tour. I was freezing in just a t-shirt in the middle of July. I also was happy that I'd taken the relatively gentle North Fork tour rather than the windswept, high-altitude Trail Ridge Tour. Plus the North Fork riders get to enjoy the awesomely delicious cinnamon rolls from the Glen Haven General Store.)

If you're looking for a good meal in Estes Park, consider the Rock Inn, which we found to have a comfortably casual atmosphere, welcoming service and even some organic ingredients on the menu (coffee, tea, apples, quinoa, etc.). You might also enjoy the unbeatable lakeside view in the Shores Restaurant at the Lake Shore Lodge hotel.

The clear mountain air and high elevation make Estes Park a lovely place for star-gazing. Amateur astronomers will get a thrill out of visiting the newly-opened Estes Park Memorial Observatory with its 16-ft. diameter observatory dome, its Meade 12-inch LX200 Schmidt-Cassegrain telescope and its gracious staff. The observatory has two open houses scheduled for August (15th and 29th), but I believe you can make appointments to visit on your own at other times by emailing the observatory directly.

Pawnee National Grassland - For most tourists, Colorado equals mountains for skiing, hiking or just sightseeing. But the fact is that much of the Eastern section of the state consists of high prairie. Most of this high prairie has been developed for farms, ranches or cities, but you can still see nearly 200,000 acres of the grassland in their native form at the Pawnee National Grassland.

This is definitely the road less traveled. Conditions can be extreme on the grasslands - very hot and dry in summer, dangerously cold and snowy in winter. But if you've got a hankering for wide open spaces and a desire to see something like the views that the first caucasian settlers must have seen as they crossed the plains, the grassland can't be beat.

As a bonus, the Grassland has a reputation as a world-class birding destination where bird enthusiasts come to see raptors, hawks, burrowing owls, thrashers, lark buntings, numerous kinds of sparrows and literally hundreds of other species of birds. Guides to the Pawnee National Grassland urge birders to do their birdwatching from the car so as not to disturb birds or scare them away from nests. Since the Grassland is actually a patchwork of private and public land, staying on the numbered roads is also essential. And since many of those roads are unpaved and not even graveled, be sure to check the weather reports since rains can apparently make many of the roads impassable.

If you come to the Grassland, make a point to seek out the Pawnee Buttes, remnants of an ancient landscape that has been mostly eroded away by the action of wind and water over millions of years. A hiking trail leads to the base of the Buttes - just be sure to watch your step to avoid cacti and prairie rattlers.

If you'd like to spend a night out on the grassland, you can try to get a room at the West Pawnee Ranch B&B. For more creature comforts, the most convenient urban base close to the Pawnee Grassland would be the city of Greeley, an interesting place in its own right that began in 1868 as a utopian agricultural colony founded by Nathan Meeker, agricultural editor of the New York Tribune. Meeker named the town after his editor at the Tribune, Horace Greeley, whose name has become inextricably linked with the 19th Century ralling cry, "Go West, young man, go West and grow up with the country."

Today, the country has certainly grown up and moved on. The countryside that Americans like Meeker, Greeley and others knew less than 150 years ago has mostly disappeared, but remnants like the Pawnee Grasslands endure and provide a glimpse back into another world.

Well...even the view isn't quite untouched. On the horizon, a line of bluffs marks a boundary with Wyoming and a wind farm atops the bluffs provides an inspiring clean energy sight. I think this might be the Ponnequin Wind Farm owned by Xcel Energy.

If your curiosity for the Pawnee National Grassland has been aroused, definitely check out these gorgeous photos of the Pawnee Buttes by Rick Dunn.

(I didn't get to spend as much time as I would have liked in Greeley, but the town seems to be home to some interesting cultural attractions including Kress Cinema & Lounge and The Greeley Philharmonic - oldest continually running orchestra between St. Louis and San Francisco!

Afterthoughts -

1. Prius - I had a chance to drive a Toyota Prius for the first time in Colorado - not the new 3rd-generation Prius but the second-generation version. I'll save a full review for when I get a chance to test drive the 3rd-generation car, but generally I was very impressed with the vehicle. Green Car Congress notes that the 1st generation Prius had a combined mileage rating of 41 mpg, the 2nd generation car had a mileage rating of 46 mpg, while the 3rd generation Prius has a combined mpg rating of 50 mpg.

Amazingly, even at high altitude and with lots of uphill mountainous driving (and of course lots of corresponding downhill rides), I managed to get over 50 mpg in the 2nd generation Prius. This gives me great home for achieving even better mileage in the 3rd generation car. I found the car's feedback system simultaneously exciting and annoying -- I liked knowing exactly what impact my driving habits were having on fuel efficiency, but I also found that it distracted me a bit from the road, the scenery and the pleasures of driving.

Still, in the end, 50+ mpg can't be beat. I loved driving around Colorado for a week and then topping up the tank for $16 and change.

2. Denver Airport Solar Array - On my way back into the airport to fly home to NYC, I noticed a large solar array on the approach to the airport. This is certainly the biggest airport solar installation I've ever seen and one of the biggest solar arrays I've witnessed firsthand. Information online indicates the array generates more than 3 million kWh of electricity, enough to provide half the energy for the underground train that connects the terminals at DIA.

I also noticed that some of the limited-access highways near Denver allow bicycling on the shoulder of the road. What do you think of that? Clever idea or recipe for disaster?

Energy alternatives article from Nature Magazine

We interrupt our regularly scheduled programming (24/7 reviews!) to recommend this interesting article from Nature on various methods of generating electricity without net carbon emissions.

I came away from the story with a renewed appreciation for the potential of solar power in particular. Consider this excerpt:
Earth receives about 100,000 TW of solar power at its surface — enough energy every hour to supply humanity's energy needs for a year. There are parts of the Sahara Desert, the Gobi Desert in central Asia, the Atacama in Peru or the Great Basin in the United States where a gigawatt of electricity could be generated using today's photovoltaic cells in an array 7 or 8 kilometres across. Theoretically, the world's entire primary energy needs could be served by less than a tenth of the area of the Sahara.

Exciting stuff! Let's get cracking on those giant solar arrays!! :)

Japan Eco-Travel: Solar Shopping Mall, Electric Bikes and Oasis 21

I recently returned from a few weeks in Japan.

Naturally, during my trip, I kept my eyes open for the latest and greatest eco-news to share with 1GreenProduct.com readers. Here's what I found:

1) At a remodeled Aeon shopping mall near the western city of Yonago, I found huge sections of exterior wall had been lined with solar panels. As a result, practically the entire building functioned as a solar collector. Other parts of the mall structure were covered in "living wall" type greenery. This eco-minded mall even had mini windmills perched on poles in the parking lot. The mall's remodeling had let in more natural light, allowing for a reduction in energy spent on artificial lighting.

Meanwhile, I found an electric bike on display at the mall. Having never had a chance to actually ride one before, I hoped to be able to test it out. In one of those comical cases of misunderstanding that often occurs abroad, the salesperson assured me that I could indeed test the bike. But I soon found this meant only that I could sit on the bike as long as I remained still and did not pedal it anywhere. This didn't really end up being a very useful test of the bike's electric functionality.

America has giant shopping malls. America has a lot of parking lots. Surely we could be retrofitting some of our shopping centers with solar panels and windmills as Aeon has done in Yonago. All it takes is willpower and imagination.

2) In the city of Nagoya, I took a break from seeing castles and museums to visit Oasis 21. This transit center / park / shopping mall / futuristic spaceship-style structure located in the city's Sakae shopping district certainly makes an impression.

What makes it eco? Well, the roof of Oasis 21 consists of a very shallow oval pool of water. The water reflects heat, cooling the ground-level plaza and the open-air below-ground shopping center.

Even better, the roof also collects rain water, which it then uses to irrigate the plantings in the park below.

Plus, it makes for a pretty cool place for couples, families and businesspeople on a lunch break to come sit, contemplate the reflecting pool and gaze at the TV Tower and the rest of Nagoya's high-rise skyline.

I like Oasis 21's boldness. There are surely less expensive ways to collect rain water, but Oasis 21 places Green ideas on center stage in one of the city's trendiest districts, showing that eco can be sexy, eco can be dramatic and eco can be architecturally beautiful.

3) I won't dwell much on the differences between Tokyo's mass transit systems and the subway system that I endure in my hometown of New York City. To think too much on the topic would probably reduce me to tears.

In brief, the Tokyo metro is clean, modern, unoffensive, safe, smooth and quiet.

The New York subway is none of those things.

But what I really would like to draw attention to in this adjacent photograph is the fact that some of the newer Tokyo metro stations have walls of glass or plexiglass (not sure of the exact material) separating the platform from the tracks. When the train arrives, the doors of car line up with sliding doors in the glass walls and both open simultaneously, allowing passengers to exit and board the trains.

As a result, I believe that it is practically impossible to be pushed in front of a train in the Tokyo Metro.

In New York, on the other hand, the narrow and crowded platforms present a definite hazard, particularly during rush hour when a few inches or a shove from behind is all that separates a passenger from the fetid tracks and injury or death beneath an onrushing train.

Given the general state of dilapidation and disrepair in the NY subway, it seems highly unlikely that protective glass doors like these will be installed anytime soon. This is a sad commentary on the extent to which America has fallen behind in mass transit best practices in comparison not only with Japan, but with other countries like France where such systems are being installed.

4) Finally, not quite satisfied with my brief test of the e-bike back in Yonago, I found an opportunity to rent an electric bike in Tokyo at a Muji store.

For around $15 and a deposit, I had the e-bike for the entire day. This was my first time ever using an electric-assist bike and frankly it was amazingly fun.

The bike was electric-assist - meaning that it would not move unless the rider pedaled. But pedaling up even the steepest hills was no problem with the electric motor on maximum assist. On flatter terrain, I left the electric assist on low or medium settings in order to stretch out the battery life.

Using an e-bike feels like someone is giving you a gentle push from behind, like when you were first learning to ride a bicycle. The freedom and speed that an e-bike provides is exhilarating, almost giddy.

At the same time, you do still get some exercise pedaling an e-bike around town for a few hours. But what would have been exhausting without electric assist was merely a nice bit of exercise with the motor providing support.

Incidentally, in Tokyo, bicyclists are allowed to use the sidewalks. This made for some extremely interesting close-quarters maneuvering when the office crowds emerged for the lunchtime rush.

(Oh, another cool thing about the Muji e-bike, which apparently is true of all sorts of bikes sold in Japan, is that it has an integrated lock built right into the bike. Turn and take the key with you when you dismount and a bolt shoots through the wheel, making it impossible for anyone to pedal off with your bike. As a result, no one has to carry around a chain or even a lock to secure their bike to a post or tree. Very convenient and easy. Would love to see this feature on bikes sold in the U.S.! Perhaps it is available here already on some models?)

The Muji bike retailed for approximately $800. Unfortunately, Muji stores in the States don't seem to carry the e-bike, but you can find various electric bikes if you shop around on the Internet or perhaps at your local bike shop.

Amazon sells some e-bikes for reasonable prices, but the $372 eZip Trailz bike appears to use an old-fashioned sealed lead acid battery, whereas newer e-bikes are using lighter and slimmer lithium ion batteries. The Ohm e-bike looks pretty cool, but apparently goes for around $2000.

Based on my experience in Tokyo, I believe that an e-bike could be a real commuting option for people who live fairly close to work (say within 10 miles) and have a relatively safe biking route available. Given the importance of having a comfortable, safe and enjoyable ride, you might want to go to a local bike shop and try out a couple e-bike models in person. If your shop doesn't carry an e-bikes yet, encourage the owner to start bringing e-bikes to the market.

I'm a believer. I think once people get a chance to try out an e-bike, they'll be hooked.

Traditional Medicinals Teas

I've been a big fan of Traditional Medicinals teas for years ever since a box of Echinacea Throat Coat (R) took care of a stubborn sore throat.

I don't recall if Traditional Medicinals teas were organic back then, but many of them are certainly organic now.

For example, take the Organic Chamomile tea (recommended for its calmative and digestive properties) that contains 100% USDA-certified organic ingredients and 100% Fair Trade Certified ingredients by dry weight.

Organic Peppermint (recommended for healthy digestion) also contains 100% organic ingredients. Organic Smooth Move herbal laxative tea with Senna leaf is 98% organic. You get the picture.

But what really gets us excited is the fact that Traditional Medicinals has just installed a large solar power system at its California headquarters, prompting the company to claim the title of "largest sun-powered tea company in the world!" The system's 1,450 solar panels are designed to generate 430,000 kWh of electricity per year -- more than 75% of the Traditional Medicinals' needs.

If you're wondering about where Traditional Medicinals gets the rest of its electricity, the company apparently supplements its solar power by purchasing wind energy credits.

(Traditional Medicinals says that it also tries to bring the benefits of solar power to some of the communities that supply its tea. In Rajasthan, India, the company says it is providing solar training, solar ovens for cooking and solar lights for night school education to the Bishnoi farming community that provides Senna leaves for Traditional Medicinals teas.)

Where to buy:

You can order Traditional Medicinals teas online from the company's own website (usually $5.49 for a box of 18 teabags) or find the teas in stores at Whole Foods Markets, Vitamin Shoppes ($3.99-4.99) and numerous other natural products retailers. Use the Store Locator to find the most convenient retail location near you.
