Fluvial Environments

Fluvial Deposits at Vasquez Rocks County Park: Fluvial Deposits Near Oberlin,OH: Ancient Fluvial Deposits near Lake Louise, Southern Canadian Rockies:

The following photographs were taken by Jeff Mount during the Integrated Watershed Science class trip down the Kaskawulsh River, Yukon (funded by his Roy Schelman chair). This river was dammed by ice from the toe of a glacier, which created a very large lake. The ice dam broke catastrophically, producing a huge flood. The flood waters transported very large volumes of sediment in huge dunes. After normal river processes resumed, the river eroded into the flood deposits, exposing the cross stratification in these impressive dunes.
