North Fork Falls is a 24-foot waterfall on North Fork Coal Creek in King County, Washington, in the Puget Lowland region. It lies about 1.1 miles east of Newcastle and roughly 5.5 miles northeast of Renton as the crow flies.
At 24 feet it is on the modest side for Washington, where the typical waterfall with a recorded height stands around 82 feet; it ranks 837th of 941. By form it is a veiling waterfall, a thin sheet of water spread over the rock face, combined with a horsetail character.
The Puget Lowland is a glacially shaped basin of low hills, lakes and wetlands between the Olympics and the Cascades, once covered by Douglas fir and western red cedar and now the most settled part of Washington. Streams here run through terraces of glacial till and outwash, with waterfalls where creeks cut through the deposits.
