Moses Coulee glaciation on the Waterville Plateau includes polished and striated bedrock, glacial erratics, drumlinoid topography, eskers, moraines, meltwater channels, and glacial till. The Withrow Moraine complex marks the maximum southern extent of the Okanogan Lobe, and a series of recessional moraine complexes represent retreating ice margins. Ice damming of the Columbia River formed Glacial Lake Columbia and Lake Spokane, larger lakes than Lake Roosevelt, which is currently backed up in the same location behind the Grand Coulee Dam. A precursor to glacial-flood-cut Moses Coulee existed prior to the glacial floods as a drainage basin with a number of side streams, draining
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
