Since late last year the Ice Age Floods Institute has been working with Eastern Washington University to produce a new map showing the extent of the temporary and semi-permanent lakes associated with the Ice Age Floods. Those efforts are about to bear fruit as the new map is about to be printed to be offered in the IAFI Store.
The map is in a format similar to our very popular “Ice Age Floods in the Pacific Northwest” map and will come in two sizes, 11:x17″ and 24″x36″. The depicted extent of the temporary lakes and their maximum elevations are based on the best research evidence of stranded erratics and other indicators. An inset in the map also depicts the elevations and maximum water depths of each of the major temporary lakes. The map also depicts the general extent of the offshore Astoria submarine fan where the bulk of the sediment carried away by the Floods was eventually deposited.
The temporary lakes are a critical part of the Floods Story and recognizing their apparent areal extent is an important key to recognizing the size and scope of the Ice Age Floods
