Double O Arch
Way back in the Devil’s Garden area of Arches National Park is the beautiful Double O Arch. This photo is looking north, after you pass through the bottom arch and climb up a small hill to look back towards the trail.
The arches are incredible. At one time this park was a mound of salt beds, which were replaced in some places with sandstone. Water eroded the salt beds, and water and wind eroded the sandstone where with just the right amount of hardness and pressure these arches remain. Since 1970, 43 arches have collapsed due to erosion with somewhere over 2000 still remaining.
