Gossamer Falls is a 102-foot waterfall in King County, Washington, in the North Cascades region. It lies about 7.1 miles northeast of Tanner and roughly 22.5 miles east of Sammamish as the crow flies.
At 102 feet it is taller than the typical Washington waterfall of about 82 feet, ranking 394th of 941 with a recorded height. By form it is a veiling waterfall, a thin sheet of water spread over the rock face, combined with a horsetail character.
The North Cascades are a wilderness of jagged peaks, glaciers and deep, forested valleys of western hemlock, silver fir and Douglas fir, with some of the heaviest snowfall in the country. Meltwater from glaciers and snowfields pours down thousands of feet of cliffs in countless cascades and horsetail falls.
