Arches National Park - Double Arch

Double Arch, within the Windows Section of Arches National Park, is so named because the two arches are joined at one end. This arch is also an example of a pothole arch, and was formed by water flowing from the top of the rock rather than against the side. The southern arm is also notable for being the second-longest span in the park at 144 feet across. Go to Photo Collection

Description Juniper remain nearly unchanged in 45 years near Double Archs in Arches National Park. A wide trail leads to the arches in 2006, and considerable erosion since 1961 has cut down the soil surface around the trail.

Description Soil erosion is evident throughout this rainy-day scene of Double Arch in Arches National Park. The trail has widened by 50% in the previous ten yeras, and many small shrubs along the trail are standing dead with exposed roots. Vegetation upslope from the trail is becoming buried in new sand dunes as the trampled soils have become increasingly unstable. Juniper and pinyon aaway from the trail continue to thrive and a few young plants have joined the scene.
