Painted Dunes And Snag Lake In Lassen Volcanic National Park Stock Photo

Painted Dunes, Lava plains and Snag Lake in Lassen Volcanic National Park, California, USA as seen from the summit of the adjacent Cinder Cone. The Painted Dunes are pumice fields that formed from layers of oxidized volcanic ash. The ash became so vividly oxidized and colorful because it fell atop a bed of lava flows while still hot.
