Behemoth Falls is a 30-foot waterfall on Cispus River in Skamania County, Washington, in the Cascades region. It lies about 31.3 miles southeast of Morton and roughly 59.2 miles west of Yakima as the crow flies.
At 30 feet it is on the modest side for Washington, where the typical waterfall with a recorded height stands around 82 feet; it ranks 766th of 941. By form it is a plunge, where the water drops vertically and loses contact with the rock face, combined with a punchbowl character.
The Cascades are a high volcanic range of snow-capped peaks, deep glacial valleys and dense conifer forest of Douglas fir, western hemlock and true firs, with abundant rain and snow on the western slopes. Basalt cliffs and lava flows give the region one of the highest concentrations of waterfalls in the country. Cispus River carries 4 recorded waterfalls; the biggest of them reaches 120 feet.
