Crater Lake is the deepest lake in the United States, reaching 1949 ft at its deepest point.[1] The national park surrounding the lake was established in 1902 and is the only national park in Oregon.[2] Around 5700 BCE, a tremendous volcanic eruption caused the collapse of the volcano known as Mazama, which lost 2500 to 3500 ft in height, and the resulting caldera gradually filled with water over approximately 740 years to become Crater Lake.[3]

Geography and history

The 1929 edition of O Ranger! described that Crater Lake National Park was reached by train on the Southern Pacific Railroad lines into Medford and Klamath Falls.[4] The elevation of Crater Lake's caldera rim varies between 7000 and 8000 ft.[5] At 6178 ft, the lake's surface elevation is the official benchmark measurement taken by the United States Geological Survey.[5] No streams either enter or exit Crater Lake.[5]

Crater Lake National Park is classified under the Köppen system as having a dry-summer subarctic climate, designated Dsc.[6] At higher elevations, particularly around Crater Lake, snowfall is frequent; data from park headquarters, situated at 6475 ft, indicates that this location receives more snowy days than any other long-term weather station in Oregon.[7]

What the cited sources add

That expedition sounded the depth at 168 different points using a piece of pipe on piano wire, and their deepest sounding of 1996 ft was very close to the modern official depth.[8][9] That same paper explains that the eruption created a large caldera, which, influenced by the climate at the time, took about 740 years to fill with water.[3][10]
