NABSQNO 12S-605521-4278068 Utah MAP
Former NABS President Bob Moore takes a GPS reading at Skywalk Arch, which is located on top of a sheer 400-foot cliff on an isolated sandstone butte called Big Mesa, northwest of Moab. The only access is to climb up the opposite side of the mesa, a journey which requires an all-day strenuous hike and good route-finding skills. Consequently, the arch has had very few visitors.
