The days of poop-behind-a-rock be gone - a Nepali climber has recently started promoting the use of a packable toilet for hikers up the world's tallest mountain. Tired of the 965 kilos of waste he picked up during an expedition in May (including a corpse dating back to 1972! wtf!), Dawa Steven Sherpa is determined to make Mt. Everest a cleaner place.

His solution is the Luggable Loo – a portable bucket-cum-toilet that stores waste in a gas-impervious bag. This way, hikers will have a potty to sit on (plus!) but poop to haul out (not so much plus). The bags do their job to keep unwanted aromas from reaching expeditionists while they hike.

Still, if hauling your own waste out seems like too much trouble, what the hell are you doing climbing Mt. Everest anyway? Any good hiker knows that the first rule of messing with Mother Nature is to leave her exactly as you found her. That includes poop, too.

The loo retails from Cabela's Outfitters for $15 – not too shabby – and 6 of the "Doodie Bags" (as they are so named) will cost you $12.99. If I were Mr. Sherpa, I'd be handing these things out at the base camp. Who wants to clean up someone else's 20-year-old, iced-over poo anyway?

Know what's weird? Woices.com.

Woices.com is a website where you can upload echoes you've recorded anywhere in the world. That includes the parking ramp.

Echoes have been recorded in cathedrals, canyons, and everywhere you can imagine. These 48 echoes were all recorded at Cerdanyola del Vallès in Spain alone!

What's the point? We're not sure. But the idea is pretty neat. It's certainly a new kind of information you're not used to getting without visiting a place!

Woices is still small now and needs your help. What a good excuse to call out the names of your loved ones or curse your ex-girlfriend over a cliff! Shout something somewhere and record it. Why not?

It wasn't until I saw this video that I remembered the whirring sound that the pulleys of a zipline make as they zip along the cables, whizzing people from tree to tree.

Although the quality is a bit grainy, the essence of the Hocking Hills Canopy Tour are captured here in just a few minutes. I posted about my personal experience a couple of days ago, but the video is a way to bring you along for the ride.

The people who filmed this, and posted it on YouTube, held a camera at such an angle that it feels as if the viewer is on the trip as well. There's also footage of one of the rope bridges you walk across during the tour. After the last zipline, there's a rappel down from the last platform to the ground. That part is also included. Plus, there's a mix of music and conversation. Nice touch.

There are some people who are determined to not wear clothes in the great outdoors. There are the people who do naked rock climbing, people who hang out on a nude beach (or play volleyball in the buff on a beach like those I saw once in Greece), people who sky dive nude, dance in the nude, go on cruises in the nude, and, like this German guy I read about, people who prefer to hike in nothing but a good pair of shoes.

Even jail time is not dissuading this German fellow from his naked hiking habits, according this Reuters article. This fellow was put in jail for ten days for in the buff walkabouts, but has vowed that he will continue to hit the trails without clothes even though it is against the law. Perhaps he sees a double standard? Hiking in the nude breaks Germany's indecency laws, although nude beaching it is okay in designated areas.

Interestingly, Germany has a German Nudist Association which is part of the German Sports Association. Nudism can be traced back to Germany as a way to be healthier, so the association fits the idea of fitness. This membership has created an increase in nude hiking love. Nude jogging also has a following, but loping along in just socks and running shoes also lands a fine.

In a way, one could say that if there are nude beaches there could be nude forests and nude mountains for those who like to scale cliffs. Whatever they do, I hope they're using a decent sunscreen.

Many seasoned backpackers are aware of Bolivia's "most dangerous road" in the world. If you want that kind of excitement--and perhaps more so since this is a hiking trail--check out China's Huashan trail, a very doable itinerary if you happen to be in Beijing for the Olympics.

To do justice to the experience, see the pictures here and here. Words can't describe some of the harrowing sections of the trail--which, again, is suppose to be a hiking trail. That means no climbing gear is available. I can easily see people falling to their deaths, and apparently because of China's less-than-stellar press freedoms, many deaths are kept quiet.

To get there, fly into Xian, which can take up a whole series of posts by itself (terracotta soldiers are there, for one). Then take the minibuses that run from the train station directly to Huashan. Or you can take the train, which drops you off some 25 km east of the mountain.

Two months ago I went rappelling in the Hocking Hills State Forest with Earth, Water, Rock Adventures Ltd.

I was pretty proud of myself that all I ended up with was a scrape on my calf when I slipped on some moss on my first time down the rock face.I could have scrapped a lot more if I had followed the thrill of nude rock climbing.

There is a trend where people cast off their clothes to experience nature from high places in the buff. The trend seems to have started in California, but has been transported to Great Britain as well.

The friend who sent me the article to the naked Barbie on the dash board story sent me this article about nude rock climbing. All I could think of when I read this story was that Jerry Seinfeld episode where he had a girl friend who insisted on being nude as much as possible. Jerry wasn't too thrilled, particularly when she attempted to open a pickle jar.

Nude rock climbing would probably really set Jerry on edge. It certainly brings being naked to a higher level.

Dean Fidelman, a rock-climber and the guy who took this picture has made a calendar dedicated to this endeavor. The project is called Stone Nudes.

His work reminds me a bit of Spencer Tunick's, another artist who sees the human form as one that lends itself well to being photographed sans clothes in nature. There is a simplicity that is very alluring.

Travel health and the emerging specialty of "wilderness medicine" have obvious overlap. Dr. Paul Auerbach is one of the leaders in wilderness medicine: helping found the Wilderness Medical Society, co-author of A Field Guide to Wilderness Medicine and numerous journal articles and serving as faculty to the Stanford Fellowship in Wilderness Medicine.

His blog, Medicine for the Outdoors, is celebrating the two year anniversary. For those who haven't yet had a chance to visit, it is filled with practical information and advice for those exploring their environment and wanting to come back from the experience in good health. Travel and expedition medicine is the focus of my career and I find myself citing Dr. Auerbach's work and information, in my work. He is one of the pioneering physicians who helped elevate this field of medicine to a new and unique specialty.

A visit to his blog will allow the reader to learn about things from jellyfish stings and dislocated shoulders on the trail to malaria medications and outdoor recreation. This is truly an opportunity to read, first hand, the information from a leader in wilderness and expedition medicine. I highly recommend a visit to his blog, if you get a chance. Oh, and don't forget to congratulate him on his two-years of dispensing great advice!

Here's another version of canopy tours, much different than the ones in Hocking Hills, Ohio and near Kuala Lumpur. At the Ysterhout Gorge in Magaliesberg, South Africa, trees are sparse, but the gorge is mighty. This is a well-done edited version that shows each step of the experience. The scenery is gorgeous. The family in this video consists of a young girl as well. You really know how much you trust a tour guide when you send your child flying along a cable, feet dangling high above the rocky ground. There's a point where my heart would jump. Part with fright, part with their excitment--and I'm the one who once took my 3 month-old on long boat rides in Thailand, passing him above the water while he was strapped in a car seat carrier. Here is a resource to find canopy tours in South Africa, plus a Gadling post from former blogger Erik Olsen that presents options in other places.

Politics aside, this is actually pretty spectacular. Chinese mountaineering team, including a woman from Tibet, took the Olympic flame to the top of the world today, AP reports.

The team used torches designed by rocket scientists to take the flame to the peak of Mount Everest. Fueled by propane, the flame burned brightly in the frigid, windy, oxygen-thin Himalayan air thanks to technology that keeps rocket motors burning in the upper reaches of the atmosphere. The flame was carried most of the way in a special metal canister. As the team neared the summit, they used a wand to pass the flame to the torch.

Wow. All this effort just to say "we did it."

The Mount Everest climbers were struggling for breath in a live television broadcast as five torchbearers each shuffled a few feet before passing on the flame to the next person. The final torchbearer, a Tibetan woman named Cering Wangmo, stood silently on the peak with her torch while other team members unfurled small Chinese and Olympic flags. They then clustered together, cheering "We made it," and "Beijing welcomes you."

One would almost think that China and Tibet are best friends. Almost.

From San Francisco to London and Paris to India, protestors are taking to the streets to demonstrate against China's hosting of the Olympic Games. Angered by the Chinese government's refusal to meet with the Dalai Lama, as well as the continued suppression of human rights in potential breakaway regions, the world is seeking to punish China on the eve of its long-anticipated coming out party.

For travelers on the ground in China, independent tourism has never been more difficult, especially since parts of the country have now been entirely closed off to the outside world. Following wave of violence that commenced on March 14th, the Chinese government has entirely barred tourists from entering Tibet. As a so-called 'autonomous region,' non-Chinese nationals must obtain special entry permits for Tibet.

Sadly, it's looking like the 'Roof of the World' may remain in relative isolation until the Olympic Games have passed, which is a huge blow at a time when tourism in the region was beginning to flourishing. Here in Japan, this was highlighted recently in the news when Mr. Yuichiro Miura, the 75 year-old thrill seeker who once skied down Everest using a parachute as a brake, announced that he was changing his Everest climbing route.
