They work with the BLM and such with establishing trails as well as maintenance and such. They actually get paid and funding I believe. They have trail ambassadors that go around to the crags and interact with the people who are doing their thing whatever it might be. After 25 years in Moab I don't climb at wall street anymore. I drove down Potash Road on Sunday for a drive and just looked the other way, it pains me to see all the A-Holes climbing after the rain. Don't climb on sandstone after it rains is in every guidebook about Moab, at the climb shops, on Mtn Proj, and at many of the trail heads. Trailmix was responsible for the signage at the Ice Cream Parlor and at Takeout Beach.
