Lower Mesa Falls

Lower Mesa Falls drops 20 meters over volcanic rocks, creating a cascade along the Henrys Fork of the Snake River at 1,682 meters elevation.

The formation of Lower Mesa Falls resulted from a supervolcano eruption one million years ago, which created layers of rhyolite tuff and basalt lava.

The waterfall remains in its natural state after local communities opposed plans for hydroelectric development, preserving this geological formation for future generations.

Visitors reach the falls through a paved 0.1-mile trail from the parking area, with wheelchair-accessible viewing platforms offering clear views of the cascade.

The falls showcase dark vertical cliffs and scattered boulders that demonstrate the geological processes of the Yellowstone region's volcanic past.
