I found an International Space Station photo taken by Thomas H. Marshburn of Crater Lake. The lake stands out from even that height above the Earth.
This made me wonder about this lake that I knew nothing about.
Crater Lake is in a National Park, managed by the National Park Service. It is the only national park in Oregon.
The two maps. The first is the EPA ( Environmental Protection Agency) US map of the states. I drew the blue line around the state of Oregon.
The second map is of the county in Oregon where the lake is located, It is called Klacmath County. It is in the South Central part of the state. This map is from English Wikipedia.
Some facts about this lake.
It is called a caldera. It’s in the Mazama volcano that erupted and erupted a lot. The top of the volcano, before it erupted, sank way down into the inside. It is not a crater from magma spewing out and leaving a hole int volcano. The inside of the volcano collapse. It is more complicated than that, but beyond me. If you want to know the details, you are on your own.
The water partly fills this hole. The average depth is 1,148 feet. The maximum depth is 1.949 feet.
This is a bathymetry survey by the US Geological Survey, Department of the Interior.. In other words, it shows the different depths of the lake. The colors show orange as less deep, to blue which is very deep.
This shows the whole lake by, Zainubrazvi.
