Thanks to Joe Poulton for adding this peak.

The Twin Sisters Range is the largest exposed section of Olivine Dunite in the Western Hemisphere. To reach the North Twin. Drive Hwy 542 (Mount Baker Hwy) East past Hwy 9 to Mosquito Lake Road. Continue south on this until you reach Logging Road 38. Head East on this staying right at all forks. You will park at the gated bridge. During summer bikes will speed up the ascent and descent. During Winter...have fun and don't forget the snowshoes. Yeagar's on Northwest in Bellingham has Logging road maps. Then on West Holly there is Basecamp to supply you with climbing equipment needs. The West Ridge is the fun route in Winter or Summer. The fastest descent is the North Face (not recomended in winter).
