The Painted Dunes are multicolored pumice fields formed by oxidation of volcanic ash as they fell out of volcanic eruptions that have sculpted the area inside Lassen National Park in Northern California. The ash on Painted Dunes is brightly oxidized because it fell on lava flows when they were still hot. The Painted Dunes, along with Fantastic Lava Beds, and other eccentric geological features lie near Cinder Cone, a 700-foot tall cinder cone volcano that’s believed to have last erupted in 1650s.

Cinder Cone is composed of loose scoria – a material which began as blobs of gas-charged lava thrown into the sky during an eruption, but fell as hardened volcanic rock containing cavities created by trapped gas bubbles. Later, like many cinder cones, it was snuffed out when several basalt lava flows erupted from its base, creating what has been named the Fantastic Lava Beds.

  • As a teen my Dad went fishing here with his father. Roads were in such bad shape they had to hike miles through heavy timber to get to the lake recommended by a Lassen Ranger.
