Shoestring Falls (also called Siah Falls) is a waterfall, about 1000feet high, fed by an unnamed stream coming from Malachite Glacier in the Alpine Lakes Wilderness Area, King County, Washington, United States. It is 20feet 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 700feet. It is at 47.6313°N -121.3188°W.[1]
Nearby Sunray Falls, at 47.63°N -121.32°W, about 400feet high, shares the same cliff as Shoestring Falls and most likely shares the same creek, making the two falls count as a double drop.[2]
