description Valentine Cave Overview

Valentine Cave is a lava tube in Lava Beds National Monument in northeastern California. It formed when the surface of a basaltic lava flow cooled and solidified while molten lava continued moving beneath it, leaving an elongated underground passage after the flow drained. The cave is known for broad passages and relatively smooth walking surfaces, making it one of the monument's more accessible lava-tube environments.
