I took these pictures last September at Crater Lake here in Oregon. Crater Lake was formed 7,700 years ago when a volcanic eruption caused the 12,000 ft Mount Mazama to collapse. It is 1,943' deep which makes it the deepest lake in the United States and the 7th deepest in the world. The fresh water is so clear and is a gorgeous shade of bright blue. It is certainly a place that must be visited in Oregon!
