The "20-20 Challenge"
Posted: May 31 2008 9:41 pm
Hey, anyone heard of the Arizona "20-20 Challenge"? It is found at az2020 The gist is to hike the 20 highest peaks and 20 deepest canyons in the state.
Here is an excerpt from it:
Here's how we selected the forty most challenging hikes in the state for Arizona's 20-20 Challenge: All canyons and summits in the state are identified by processing digital elevation models (digital topographic maps) in a geographic information system. From this list, we drop all canyons and summits that do not have trails, are located in environmentally protected land, or in some cases, are on private land. Next, the peak and canyon hikes must pass our challenging set of geomorphic, geometric, proximity, altitude, and/or trail length criteria. The remainder is forty truly challenging hikes!
Also attaching a shot of their top 20 hikes. Sounds like a fun challenge!
