Contrasting views on how public lands should be managed and enjoyed collided in a congressional committee hearing Thursday as distinct lines were drawn over whether more than 9 million acres of red-rock landscape in Utah's outback should be protected as official wilderness or left open for off-road vehicles, mountain bikes, and energy development.

Most of us go out of our way to avoid a "fiery furnace" situation, but many visitors to Arches National Park are the exception. Ranger-guided hikes into the park's version of the Fiery Furnace often fill in advance, so the park is experimenting with online reservations through the end of October.

Slipping from the top of the arch into the abyss below was a difficult move that rattled my psyche. Even though the sandstone band I was perched on was not much more than 4 feet wide, it was stable. Putting my faith into the rope cinched to my climbing harness and dropping into the 100-foot void went completely against my desire for self-preservation.

Canyonlands National Park is one of the most rugged national parks, with a harsh summer sun that bakes the dry, canyon-riddled landscape. But those deep canyons’ steep rocky slopes, which offer ample grasses and shrubs, and an openness that puts predators at a disadvantage, are an optimal environment for bighorn sheep. In fact, Canyonlands’ bighorn population has been so stable that Utah’s wildlife biologists long relied on it for stock to re-establish herds elsewhere in the state.
