Shoestring Falls (also called Siah Falls) is a waterfall, about 1,000 feet (300 m) high, fed by an unnamed stream coming from Malachite Glacier in the Alpine Lakes Wilderness Area, King County, Washington. It is 20 feet (6.1 m) in breadth and flows year-round, but is at peak flow May to July. It drops down the mountainside in five distinct tiers, with the two main tiers totaling about 700 feet (210 m).
