Palouse Falls
A waterfall dropping about sixty metres into a basalt amphitheatre in eastern Washington, cut by ice age floods.
Updated 21 October 2026
The falls drop about sixty metres into a circular basalt basin, and the canyon around them is a product of the Missoula Floods - repeated ice age outburst floods that scoured the Columbia Plateau and left the coulees, dry falls and channelled scablands across eastern Washington. The Palouse River now runs through a channel far larger than it could have cut. It was made Washington's state waterfall in 2014 after a campaign led by schoolchildren. There is no legal trail to the base and the informal route down is dangerous, as is swimming above the lip; the park has fenced and closed routes. Flow is strongest in spring and drops substantially by late summer.
