2017 Map of Allen Valley
USGS Topo · Published 2017About this map
Allen Valley characterizes this high plains landscape in Cherry County, where the hydrology is dominated by the North Loup River winding through the northern reaches. The area is defined by its complex wetland systems, including the Murphy Swamp and the expansive Marsh Flat surrounding Marsh Lake. These features, along with Humpert Lake, suggest a terrain shaped by the unique Nebraska Sandhills ecosystem, where groundwater and surface drainage create a network of intermittent and permanent water bodies like Big Cr and Horse Cr.
