Deep Blue / by Dave Hileman

This is Crater Lake National Park in Oregon. The lake was formed by a volcano and then the caldera, basically a hole left when the magma is expelled, settled and filled with water. It is the deepest lake in the US at nearly 2000 feet and is replenished by rain and snow. 

Bobby Vinton could have sung here. So could Dylon, Diamond and Bennet among others.
