Lake Coeur dAlene

Lake Coeur d'Alene is a characteristic lake in northern Idaho, in the northwest United States. Its northern end is in the city of Coeur d'Alene. It traverses 25 miles 40 km long and extends from 1 to 3 miles 5 km wide with more than 109 miles 175 km of shoreline. The Purcell Lobe of the Cordilleran Ice Sheet streamed south from Canada, cutting the bowl of present-day Lake Pend Oreille and damming the Clark Fork waterway.

Lake Coeur d'Alene, as different lakes encompassing the Spokane Valley and Rathdrum Prairie, was framed by the Missoula Floods, most as of late 12,000 to 15,000 years prior. The appropriated stream more than once filled to frame Glacial Lake Missoula and got through the ice dam, bringing about huge surges that filled the Rathdrum Prairie zone with sand, rock, and stones.
