Wenatchee Valley Erratics

Where the Floods Came Early and Late

Apparently, some of the earliest and some of the latest of the Ice Age Floods roared along the Columbia River through the Wenatchee area. They left fields of giant megaripples on massive point bars along the river, and back-flooded the tributary rivers that fed into the Columbia.

At places like West Bar on the Columbia, it’s easy to recognize where the field of megaripples deposited by the massive early Floods have been cut into by later, smaller (though still huge) Floods during the waning period of the last ice-age.

In the times between, the Okanagan Lobe of the Cordilleran Ice Sheet blocked the path of the Columbia River and diverted the Floods down the Moses and Grand Coulees.The Wenatchee Valley Museum and Cultural Center offers a wealth of information about the Floods, indigenous peoples in the area, and much more.
