About this map

Brock sits at the confluence of several local waterways in Nemaha County, where the Little Nemaha River is joined by Piper Cr and Houchen Cr. This landscape is defined by the winding river valley and the dispersed agricultural settlements of Glenrock and Rohrs, connected by a grid of rural roads like 736 RD and 728 RD. The topographical survey highlights the drainage patterns of the region, featuring several smaller streams such as Gauchat Cr and Opal Cr that feed into the larger river system.

Local history is preserved through the locations of several burial grounds, including Old Glenrock Cem, Clifton Cem, and Linden Cem, which serve as important markers for genealogical research. The presence of the Dominey Reservoir in the western portion of the area indicates local water management efforts within the rolling terrain of T6N and T5N. This survey documents the intersection of natural hydrology and a settled agricultural community in the early 21st century.
