CRATER LAKE NATIONAL PARK
Crater Lake is a caldera lake located in
the south-central region of Oregon.
It is the main feature of Crater Lake National Park and famous for its deep blue
color and water clarity. The lake partly fills a nearly 2,148-foot deep caldera that was
formed around 7,700 years ago by the collapse of the volcano Mount Mazama.
There are no streams feeding the lake.
Water is replenished by rain and snow melt.
This pumice desert lies on the former floor
of the valley below Mt Mazama
