Crater Lake - Freshwater Lake
Crater Lake National Park is found in southern Oregon. It is only one in a long series of volcanoes found along the northwest coast of North America. About 6,500 of years ago, the volcano Mount Mazama collapsed on itself and created a large caldera. Over many years, the caldera filled with water and created Crater Lake. The lake is the deepest lake in the United States with a depth of 1,932 feet. The lake is known for its deep blue color that contrasts the surrounding evergreen forests of the Cascade peaks. Even after the largest eruption, the volcano was still active and Wizard Island is one of the remnants of that activity. Since Mount Mazama is long gone, Mount Scott is now the highest point in the park at 8,900 feet. While there are guided boat tours across the lake, you may also receive park permission to boat, fish, and even scuba dive in the lake. Even though the lake is very cold throughout the year, there are thermal vents deep in the lake provide localized heat sources and new minerals for the water. The vents don't change the overall temperature of the lake because it is so large. While difficult to tell as you look across the surface, the caldera was once several thousand feet deep. This image was taken near Skell Channel on the west side of the lake.
