Crater Lake National Park is in the Cascade Mountains of southern Oregon. It’s known for its namesake Crater Lake, formed 7700 years ago by the now-collapsed volcano, Mount Mazama. Wizard Island is a cinder cone near the western edge of the lake. The Rim Drive, a road surrounding the lake, offers views of the park’s volcanic formations. The lake measures 4+ miles by 6+ miles in diameter. The park’s numerous trails include Sun Notch, with views of the Phantom Ship, a small island. ― Google
