Lava Canyon Falls

Lava Canyon Falls drops 200 ft along the Muddy River in Skamania County, Washington.

Formation
Lava Canyon Falls was discovered after the 1980 eruption of Mount St. Helens, from which a lahar and flood scoured out a canyon that had been filled with dirt and mud for 1,800 years. The Muddy River's course was redirected to that canyon as a result of the lahar and the floods, and it drops 1,400 ft in 2 mi. Lava Canyon Falls is the largest, 200-foot sheer drop.

Location
On the southeast side of Mount St. Helens National Volcanic Monument at 46.1701°N, -122.0826°W, at 2,440 feet.
