Crowley Lake Columns: Strange Formations, Mono County California
In the Eastern Sierra, Owens Valley sits the Long Valley Caldera. The caldera was formed 760,000 years ago depositing volcanic ash that was cemented together by heat and pressure. Today a Crowley Lake Reservoir sits in what remains of the caldera. Researchers have determined that the columns were created by cold water percolating down into — and steam rising up out of — hot volcanic ash cemented the ash into more resistant columns that were exposed by wave action of the lake water.
