Summary

The Fort Morgan 7.5' quadrangle is located on the semiarid plains of northeastern Colorado, along the South Platte River corridor where the river has incised into Upper Cretaceous Pierre Shale. The Pierre Shale is largely covered by surficial deposits that formed from alluvial, eolian, and hillslope processes operating in concert with environmental changes from the late Pliocene to the present. The South Platte River, originating high in the Colorado Rocky Mountains, has played a major role in shaping surficial geology in the map area, which is several tens of kilometers downstream from where headwater tributaries join the river. Recurrent glaciation (and deglaciation) of basin headwaters has affected river discharge and sediment supply [...]

Purpose

To provide a geologic map database showing the distribution of fluvial, eolian, and hillslope deposits along the South Platte River corridor in the Fort Morgan, Colorado area, to better understand past geomorphic system response to environmental change and the geologic framework of South Platte River corridor ecosystems.
