“Discover the Wonder of Lakehead”
Lake Shasta Caverns is one of three known caverns in the deep limestone beds of Shasta County. The beds originated 250 million years ago when the area was submerged and was subjected to folding of the earth’s crust. This ultimately created the Klamath Mountain range. Subsequent submerging, volcanic action and uplifting of the earth’s crust created the perfect environment for the formation of caverns.There are many theories on how caves are formed. Evidence supports the belief that the hollowing out of mountains begins when ground water flows through fissures in the limestone. Carbonic acid created by decayed organic matter is carried by surface water through the cracks and dissolved the softer part of the limestone. This creates a “swiss cheese” effect inside the mountain. Calcium carbonate is deposited in the voids and slowly accumulates to create calcite formations. These speleothems or formations take hundreds of years to form and come in a remarkable variety of shapes, sizes and colors. The most common formations are stalactities (hang from the ceiling) and stalagmites (grow up from the ground). Discover how many more formations there are, some quite extraordinary and all beautiful!
