Black Point:
Black Point, a volcano that erupted underwater, is an unusual sight on dry land! The eruption that spewed out this pile of black cinders occurred under a much deeper Mono Lake during one of the Mono Basin's many ice ages. As the climate warmed and Mono Lake shrank, Black Point was exposed. Its sharp cinders are minded and scattered on roads during winter to provide traction on slippery ice. |
