Crater Lake
Field Guide
The deepest lake in the United States, filled entirely by snow and rain inside a collapsed volcano.
A complete planning guide to Crater Lake National Park. Covers the eruption and collapse of Mount Mazama roughly 7,700 years ago, driving the 33-mile Rim Drive loop and its many overlooks, hiking the steep Cleetwood Cove Trail down to the only legal lake access point, boat tours out to Wizard Island, the Klamath tribes' oral history of the eruption, the mystery of the Old Man of the Lake, seasonal snow closures that keep the full rim road open only from July through October, camping and lodging from the historic Crater Lake Lodge to Mazama Village, and the official NPS park map.
