Wilson Arch

Wison Arch was named after Joe Wilson, a local pioneer who had a cabin nearby in Dry Valley. This formation is known as Entrada Sandstone. Over time the superficial cracks, joints and folds of these layers were saturated with water. Ice formed in the fissures, melted under extreme heat, and winds cleaned out the loose particles. A series of free standing fins remanied. Wind and water attacked these fins until, in some, the cementing material gave way and chunks of rock tumbled out. Many damaged fins collapsed like the one to the right of Wilson Arch. Others, with the right degree of hardness survived despite their missing middles like the Wilson Arch.
