The Reverse side design features a portion of Crater Lake, the deepest lake in the United States, viewed from the south-southwest rim. The design incorporates Wizard Island, as well as Watchman and Hillman Peaks on the lake’s rim and conifers. The coin bears the inscription Crater Lake.
Crater Lake is a unique and stunning natural treasure, formed more than 7,700 years ago by the collapse of Mt. Mazama in what is now southern Oregon. At 1,949 feet, it is the deepest lake in the United States and the seventh deepest in the world, and has a record clarity depth of 134 feet. The main cause of Crater Lake’s remarkable clarity is its isolation from incoming streams and rivers. President Theodore Roosevelt established Crater Lake National Park in 1902, with the lake itself as the Park’s crown jewel. It is the sixth oldest national park in the country. Since its creation, Crater Lake National Park has helped protect both the Native American cultural ties to the area and the natural habitat of the animal and plant life that lies within its boundaries.
