Lake Shasta Caverns
The Lake Shasta Caverns are a network of caves located near the McCloud arm of Shasta Lake in California. It was formerly named Chalk Cave and Baird Cave, named after Spencer Fullerton Baird. The caverns are dated at least 200 million years, and were formed by flowing water. Over the years this water drained leaving the caverns seen today. The caves are made entirely of limestone, and feature every type of possible formation, including stalactites, stalagmites, soda straws, columns, and flowstone. The Discovery Room, one of eight known rooms in the cavern system, contains all types of limestone rock formation. the first recorded white explorer was James A. Richardson, a federal fisheries employee. His claim of discovery is still clearly legible on the wall where he wrote it that day – November 11, 1878 – with carbide from his miner's lamp.
