Physical Characteristics
| Description |
Crater Lake was created by the eruption and collapse of Mt. Mazama almost 7,000 years ago. Crater Lake is isolated from surrounding streams and rivers by the high sides of the caldera, so there are no inlets or outlets to the lake. Crater Lake is filled with rain and melted snow that fell within the caldera basin. It took approximately 250 years for the lake to fill to its current level. |
