Salt Valley and the Fiery Furnace: Arches National Park, September 2001 Rachelle and I decided that we would hike out to Delicate Arch first thing to avoid the worst of the day’s heat. Along our way to the trailhead, we stopped at Panarama Point, where we had a view of Salt Valley and Fiery Furnace. Underlying the park is a salt bed deposited when this area was a vast inland sea. As the salt deposits dissolved, the sandstone which lies above it collapsed and was eroded in to rock slabs called “fins”. As wind and rain continued their work on these fins, sections of these rock walls fell away creating the remarkable formations found throughout the park. (via Robby Edwards’ Photos)
