- Mount Si Natural Resources Conservation Area (NRCA) (summitpost.org)
The Mount Si Natural Resources Conservation Area (NRCA) is one of the most climbed regions of Washington State. The centerpiece of the area is a steep, rugged mountain ridge spanning across the Mount Si NRCA mostly west-east (with a couple of short offshoot ridges and highpoints). Although most recreational use occurs on popular destinations Mount Si, Little Si, and Mount Teneriffe, the lesser known peaks of the area (Green Mountain, Dixie Peak, Blowdown Mountain, and Crater Lake Mountain) also offer substantial recreational opportunities for outdoor enthusiasts.
