Crater Lake is located in Southern Oregon on the crest of the Cascade Mountain range, 100 miles (160 km) east of the Pacific Ocean. It lies inside a caldera, or volcanic basin, created when the 12,000 foot (3,660 meter) high Mount Mazama collapsed 7,700 years ago following a large eruption. Crater Lake has inspired people for hundreds of years. No place else on earth combines a deep, pure lake, so blue in color; sheer surrounding cliffs, almost two thousand feet high; two picturesque islands; and a violent volcanic past. It is a place of immeasurable beauty, and an outstanding outdoor laboratory and classroom.

The deepest lake in the western hemisphere and formed by an ancient volcanic caldera rim, this spectacular lake and national park offers hiking, fishing, lodging, and unprecedented photography opportunities. The lake also features an ash desert, pinnacle formations, and other geologic points of interest. This national park is a 4 hour 206 mile drive from Marble Mountain Ranch and follows the scenic Hwy 96 Klamath River Byway for the the first half of the drive.
The beautiful state of Oregon is home to only one National Park, Crater Lake National Park. Long Hollow Ranch is a two hour and 10 minute drive from the entrance to the park. A visit to Crater Lake makes a nice day trip from Long Hollow.
Crater Lake was created over 7000 years ago when the top of Mount Mazama collapsed. The crater is 2,148 feet deep and the water depth reaches 1,949 feet. No river flows out of or into Crater Lake. Wizard Island is the notable feature in the lake, along with a relatively small pinnacle known as Phantom Ship.
Crater Lake boasts an amazingly brilliant shade of clear blue water. The lake can be circled by car and there are many trails to hike around the rim. Food, lodging, souvenirs and information are all available at the park. When you go, be sure to take your camera. Just the drive getting to the lake itself is worth recording!
