Crater Lake National Park Oregon is the deepest lake (1,943 feet) in the United States.
It is also one of the ten deepest lakes in the world. This lake sits
inside a volcanic crater. Crater Lake's formal name is Mount Mazama. Mount Mazama is a volcano that last erupted
7,700 years ago.
When it erupted, the caldera filled up with rain water and melted snow and is now called, Crater Lake. Every year, a half a million visitors come here.
Crater Lakes water only comes from the snow melt and rainfall. No rivers or streams, feed into this lake. Clean rain and snow melt is what contributes to the clarity of the water that fills Crater Lake. In fact, this lake is rated the cleanest large body of water in the world!
volcano erupted, Mount Mazama stood 12,000 feet high. Now, its 6,175 feet high. The crater is six
miles wide. This deep blue lake is surrounded by 2,000 foot high
mountains. It is a scenic drive around the crater on the 33 mile Rim

Zack And Glenn On The Boat At Crater Lake National Park Oregon
Out in Crater Lake is a cinder cone that is an island. The island is called Wizard Island and is 765 feet above the lakes water. You can hike down to the lake from the rim and take a boat ride out to the island. They will leave you on the island for three hours. When they pick you up, the boat takes you around the perimeter of the lake and gives you a nice history talk about the volcano and the lake. You can get off the boat and hike to the top of the cinder cone. A boat ride to the island is worth taking.
Crater Lake National Park Oregon is an excellent place to scuba dive. The water is clear and calm. The lake is no longer stocked with fish. However, there are still kokanee salmon and rainbow trout fish in the lake. Because this lake is the crater of a once active volcano, seeing inside the lake is really seeing inside a volcano.
There are talus slopes, volcanic cones and
landslides inside crater lake. You need to get a permit from the parks
headquarters before scuba diving in the lake. Wear a wet suite because the water is cold. The temperatures range from below 40 degrees to a high of 58 degrees. We were amazed that the water is so clear. If fact, there are parts of the lake you can clearly see down 130 feet from the surface!
