2021 Map of Green Lake

About this map

Survey Valley sits at the heart of this Sheridan County landscape, characterized by the intricate drainage patterns and depressions typical of the Nebraska Sandhills. The area is defined by its numerous small basins and wetlands, with Green Lake and Shane Lake serving as primary geographic anchors in a terrain otherwise dominated by undulating landforms and ephemeral water bodies. This region shows a sparse, remote settlement pattern where human activity is primarily traced through a network of rural routes and trails such as 358 Trl and 281 Trl. These primitive roads follow the natural contours of the valley, reflecting the historical necessity of navigating around the shifting sands and seasonal wetlands of the high plains. The map provides a look at the enduring township and range system, marking boundaries like t27n r43w and t28n r42w that continue to organize this open cattle country.
