Black Point Fissures (Mono Lake)

Mono County, CA

Coordinate verified

Pleistocene basalt volcanic cone on the north shore of Mono Lake riven by deep cooling fissures and caves—an off-trail geology hike in the Mono Basin National Forest Scenic Area. Distinct from the south-shore tufa towers: cinder slopes, fracture caves, and panoramic lake views without the South Tufa boardwalk crowds.
