Sulphide Glacier is in North Cascades National Park in the U.S. state of Washington, on the south slopes of Mount Shuksan.[2] Descending 1.85miles from the summit tower of Mount Shuksan, it is connected to Crystal Glacier to the east. Sulphide Glacier descends from 8600feetto5600feetft (toft).[2] Sulphide Glacier is along the route taken when Mount Shuksan was first climbed in 1906.[3] Both Sulphide and Crystal Glaciers have a series of 300feetto1000feetft (toft) high cascades which are collectively referred to as Sulphide Basin Falls.[4] Below these cascades lies Sulphide Lake, which empties over Sulphide Creek Falls, one of the highest waterfalls in North America with a nearly 2200feet drop.[5]
