Thornton Lakes are located in North Cascades National Park, in the U. S. state of Washington. [2] These paternoster lakes consist of three lakes located 1 to 1.75 mi (1.61 to 2.82 km) southeast of Mount Triumph. Thornton Lakes can be accessed on foot from a trailhead in Ross Lake National Recreation Area. The hike of 5.2 mi (8.4 km) includes a 2,400-foot (730 m) altitude gain and a 500-foot (150 m) descent to Lower Thornton Lake. [3] Two other lakes lie above the first one, unofficially named Middle and Upper Thornton Lakes. A designated backcountry camping zone is located at Lower Thornton Lake. [4]

Crater Lake caldera lake in south-central Oregon and main feature of Crater Lake National Park

Crater Lake is a crater lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera that was formed around 7,700 years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.
