Wenatchee WA - Ice Age Flood Features
|
Floodwater in the Wenatchee Valley traveling up to 65 miles-per-hour and 1,000 feet deep! With icebergs rafting massive boulders. | Evidence Left by the Ice Age Floods Surrounds WenatcheeWenatchee, Washington - first established at the confluence of the Columbia and Wenatchee Rivers - is nestled among beautiful landforms strongly imprinted by the Ice Age Floods of the Pacific Northwest. The floods did massive amounts of work here, but not in a way that most of us visualize. Instead of the more familiar coulee-cutting erosion by the floods, the story in Wenatchee are the Ice Age Floods depositing layers of sediment, rocks, and even house-sized boulders! |
Huge boulders shown in column at right were deposited by the Ice Age Floods. Top two images show boulders on private property [photos taken from city streets]. Boulders in lower photo sit near Columbia River pedestrian bridge - along bike path. Wenatchee Area |

Alternate US97 along Columbia River [1] north of Wenatchee and Rocky Reach Dam [2]. Point "3" in the distance is the approximate location where most of the floodwater turned east (left) and inundated the site of present day Wenatchee. Some of the floodwater was forced west (right) at location marked "3" and filled the Wentachee River valley all the way to Leavenworth, WA. |

In addition to Cunderla, several other Wenatchee area residents work hard to promote the Ice Age Floods story - a couple of them [I've met] are Ralph Dawes and Ken Lacy. Thanks guys!!!
