Twin Sisters Range

Washington > Northwest Region


Named after the two highest peaks in the range -- North Twin (6,640') and South Twin (7,000'+). Contains the biggest mass of exposed olivine in the Western Hemisphere! Not to be missed. Super solid and sticky rock.

SW of Mount Baker, just 21.5 miles from Bellingham's Samish Bay.

Getting There

Access via Blue Mountain Rd, Howard Creek Rd, or Middle Fork Nooksack River Rd.

[Hide Comment] Beautiful peaks. I often drive by them on Highway 9.

Your description of the rock types just adds to the attraction - thanks. Oct 8, 2015
