historyMcLean’s Blowout

historyDeception Crags

Crowds and parking problems at Little Si sent climbers to other cliffs along Interstate 90 in the early 1990s, and in 1994 a mini-guide in Rock & Ice magazine announced the Exit 38 cliffs, also called Deception Crags. The Access Fund organized two trail projects there in the late 1990s.
