( The route south from Alaska and the Bering Straight was blocked during
most of the Clovis period? )
Between 15,000 and 12,800 years ago we were in the last throes of the
Ice Age and nearing the end of the Pleistocene Epoch. The Cordilleran
Ice Sheet expanded southward into northern Washington, Idaho, and Montana.

A massive sheet of ice 4000 feet thick, the Cordilleran Ice Sheet had
three main lobes: The Puget Lobe which scoured out the Puget Sound, the
Okanogan Lobe which blocked the Columbia River at the site of the
present day Grand Coulee Dam forming Glacial Lake Columbia, and the
Purcell Lobe.
