About this map

The Niobrara River winds sharply through the southern half of this Cherry County landscape, creating a dramatic corridor of oxbows and steep-banked bends that contrast with the open Sandhills terrain to the north. At the time of this 1987 field check, the region was defined by large-scale cattle operations and isolated outposts, with several family-named landmarks including Arnot Ranch, Nielsen Ranch, Cobb Ranch, and the 71 Bar Ranch marking the spread of ranching heritage across the hills. The small settlements of Lavaca and Flats sit south of the river, anchoring a remote network of trails and unimproved roads. North of the river, Coffey Lake provides a rare water feature amidst the complex topography of the dunes, illustrating the specialized land use required to sustain livestock in this Nebraska interior during the late twentieth century.
