Once Volcano; is Great Lake
August 27, 1920
Crater Lake National park, Oregon, is the heart of the Cascade mountain range. In this neighborhood the Cascades merge into a broad, irregular platform surmounted by volcanic cones, which vary in size and are distributed without regularity, says Detroit News.
The fragments, blown up by violent eruption, have fallen upon the volcanic orifice from which they issued and built up cinder cones.
Crater lake itself is a body of water of wonderful blue in the blown-in top of an extinct volcano. The lake is 2000 feet deep in places, having no inlet of any sort, nor is there any stream running out of it. But the water is supposed to escape by underground channels, and to reappear as springs in the Klamath region, a few miles away. Geologists find Crater lake of special interest because of the way nature made it.
Mazama Fell in Upon Itself.
Long before man came to this region, the entire upper part of Mount Mazama fell in upon itself in some titanic cataclysm, as if swallowed up by a subterranean cavern, leaving its craterlike lava sides cut sharply downward into the central abyss. The volcano was not quenched, bursting up through the collapsed lavas in three places. The fires ceased and gradually, as the years passed, springs percolated into the vast basin and precipitation filled it with water within 1000 feet of its rim, forming Crater lake.
