The sun peeks through a skylight of Indian Tunnel on an overcast November afternoon at Craters of the Moon National Monument and Preserve. Indian Tunnel is a lava tube that formed when the exterior of a lava flow cooled and the molten interior continued to flow, similar to a river when it begins to freeze. Skylights form in a lava tube when weather or a passing animal breaks through a thin layer of the tube. This skylight is roughly 25 feet in diameter.
