Little Rock Creek Proposed Wild & Scenic River

Fact Sheet: Little Rock Creek Proposed Wild & Scenic River

Rising from the sub-alpine slopes of Mount Williamson, Little Rock Creek tumbles down the northern escarpment of the San Gabriel Mountains into the Mojave Desert.

An area of high ecological significance, Little Rock Creek provides an important refuge for endangered amphibians, including mountain yellow-legged frog and arroyo toad. The Pleasant View Ridge Wilderness in the road-less upper watershed helps maintain Little Rock Creek’s high level of ecological integrity.

The Pacific Crest Trail provides access to the upper part of the creek and its tributaries, including scenic Cooper Canyon Falls, a popular hiking destination. The entire stream offers unusual but seasonal class IV-V whitewater
kayaking for experts.
