A Major Volcanic Eruption Creates The Deepest Lake
In The United States
In The United States
66 inches of annual rainfall and 544 inches of annual snowfall feed Crater Lake. The lake is usually covered in snow nine months out of the year.
Mt. Mazama’s eruption left ash across eight states and three Canadian provinces. 5,000 square miles were covered with six inches of Mazama’s ash. In the park’s pumice desert ash lies 50 feet deep.
The deep blue water of Crater Lake is due to the lake’s depth. Light is absorbed, color by color, as it passes through clear water. First the reds are absorbed, followed by orange, yellow and green. The last to be absorbed is blue. Only the deepest blue, from sunlight, gets scattered back to the surface of the lake.
Snow plows do not usually finish their work until mid June. Visitors come to the park from June through October. But travelers should check the park’s web site, even in June or September, to ensure they can visit the lake.
