This is a trip I did a few years back with some friends in the Canyonlands. A fun and unqiue trip. Looking back I dont know why we added so much extra suffering! But it goes to show how you can ratchet up the adventure by just leaving a couple things behind, like your car, and water.
I wrote an article on it, shelved it, and never published it - I have posted it on my blog in two parts with photos. Enjoy
(this one will link to the second one)
