Moab, Utah is the mountain biking capital of the inner U.S. West and a site where industrial-strength biking occurs on federal Bureau of Land Management tracts and other public lands. But is this kind of use—where speed is a factor— compatible with a wild region like the Greater Yellowstone Ecosystem that has grizzly bears, sensitive areas used by migratory ungulates and both bighorn sheep and mountain goats in the Forest Service high country? Moab has none of these high wildlife values in play. Mountain biking use is already ratcheting up in both Greater Yellowstone's front and backcountry. Photo courtesy BLM
