Crater Lake rests in the shattered remnants of Mount Mazama, an ancient volcano. About 7,700 years ago, the volcano erupted with spec­tacular force, spreading volcanic ash and pumice over much of what is now the western United States and Canada. Eruption debris can still be seen in the soil as far away as Montana and Sas­katchewan. So much material was ejected from the volcano that is foundation was undermined, and it collapsed into itself. When the smoke cleared, a four-thousand foot deep basin was left where a 12,000 foot high mountain had once stood. Over time, rain and snow filled the basin with water, to a maximum depth today of 1,943 feet. Volcanic activity continued, building Wizard Island and several other features.
