Kalmiopsis Wilderness

This nearly 180,000 acre Wilderness includes the headwater basin of the Chetco and North Fork Smith Rivers and a portion of the Illinois River canyon. This is a harsh, rugged area with a unique character. Elevations range from 500 to 5,098 feet (Pearsoll Peak). The area is characterized by deep, rough canyons, sharp rock ridges and clear rushing mountain streams and rivers. Diversity of topography and geology provide excellent habitat for a wide variety of botanical species. The Kalmiopsis Wilderness is well known for it's diversity of plant life. Much of this diversity results from plant species adapting to life in harsh soils derived from peridotite and serpentinite rocks.
