Inscription. Click to hear the inscription.

Glacial activity about 9000 to 12000 years ago created this lake out of what previously had been the valley of a river.
The ice sheet occupied major valleys north of here. As the glacier receded, melt waters flooded across the outlet of this valley, beyond modern Coeur d'Alene. Rock, sand, and gravel deposited there by those floods raised the level of the land and blocked the old river channel. This backed up the river, submerged the valley before you, and produced on of Idaho's lovey views.

Erected by Idaho Department of Transportation. (Marker Number 281.)
