Sulphide Lake is located in North Cascades National Park, in the U. S. state of Washington.[2] Sulphide Lake lies in a cirque on the southeast slopes of Mount Shuksan. Several major cascades drop as much as 1,000 ft (300 m) into Sulphide Lake including Sulphide Basin Falls which is from melt off the Sulphide Glacier. After Sulphide Creek drains from Sulphide lake, it then plunges at least 2,000 ft (610 m) over a series of cascades called Sulphide Creek Falls, which is one of the tallest waterfalls in the U.S.[3]

The lake is in a basin with near vertical walls and the rock is phyllite and greenschist. Above the lake on the cliffs below Crystal Glacier a 0.3 mile wide band stained red in color (from iron oxide) is exposed that runs for about 2.5 miles. This band is rich in the iron sulfides pyrite and pyrrhotite.[4] Presumably this is the source of the lake's name.

Der Sulphide Lake ist ein Gletscherrandsee im North Cascades National Park im US-Bundesstaat Washington.[2] Der Sulphide Lake liegt in einem Kar am Südosthang des Mount Shuksan bei 48° 48′ 17″ N, 121° 35′ 2″ W48.804722-121.583889[1]. Mehrere große Kaskaden stürzen aus mehr als 1.000 ft (ca. 300 m) Höhe in den Sulphide Lake einschließlich der Sulphide Basin Falls, welche vom Schmelzwasserabfluss des Sulphide-Gletschers stammen. Nachdem der Sulphide Creek den Sulphide Lake verlassen hat, stürzt er über mindestens 2.000 ft (ca. 600 m) über eine Serie von Sulphide Creek Falls genannten Kaskaden abwärts, welche zu den höchsten Wasserfällen der Vereinigten Staaten gehören.[3]
