Crater Lake

Some volcanoes are high mountain peaks. When volcanoes erupt, magma, or molten rock from deep inside the Earth, comes out of the top of the volcano. When the magma comes to Earth’s surface, it is called lava. For some volcanoes, an eruption is not a quiet event. Lava, rocks, and other materials explode out of the volcano. These materials can travel to regions hundreds of miles away. Sometimes, so much rock is lost from the eruption that the entire volcano collapses. Then a crater, or huge pit in the ground, is left behind.

One volcano that erupted like this was Mount Mazama in Oregon. After the large eruption, Mazama continued to have small eruptions. The lava became hard to the touch and created the floor of the crater. Finally, the volcano finished erupting. Over many years, snow and rain filled the empty bowl, creating a new lake. Today it is called Crater Lake, and at 1,943 feet deep it is the deepest lake in the United States.

Crater Lake’s water is clear and deep blue. Because the lake has no rivers running into it, its water is especially pure. In fact, the early pioneers who spotted the lake wanted to name it “Deep Blue Lake.” So, whose idea was it to name the lake Crater Lake?

In July of 1869, newspaper editor Jim Sutton and several others decided to visit the lake and explore it by boat. They built a boat and lowered it into the lake. Five people reached Wizard Island at the lake’s center, and they spent several hours exploring. Sutton wrote an article describing the trip for his newspaper in Jackson, Wyoming. He called it “Crater Lake.” Maybe if you saw it yourself, you would come up with another name.
