Moses Coulee Coulee, a National Natural Landmark, one of the largest examples of bars created by the Channeled Scablands outburst floods. Moses Coulee cuts into the Waterville Plateau, which lies in the northwest corner of the Columbia River Plateau. The plateau is part of the Columbia River Basalt Group, a large igneous province that lies across parts of the states of Washington, Oregon, and Idaho in the United States of America. During late Miocene and early Pliocene times, one of the largest flood basalts ever to appear on the earth's surface engulfed about 163,700 km² (63,000 mile²) of the Pacific Northwest, forming
Grand River (Michigan) stampede, as millions of logs flowed uncontrolled down the river and became trapped in bends or against bridges. The result was a logjam of incredible proportions that clogged the river for 47 miles (10 million Feet of logs trapped in Lowell, 95 million Feet of logs trapped in the "Big Bend" northeast of Grand Rapids, 80 million Feet of logs trapped in Ottawa County). Grand River Avenue (or Grand River Road) was built early in the settlement of Michigan and runs from the head of navigation on the Grand to downtown Detroit. It formed an important part of an early
