2017 Map of North of Ryegrass Flat

About this map

The Big Lost River cuts through the western edge of this arid Butte County landscape, which is defined by a strict grid of survey lines and utilitarian access roads. This 2017 survey by the U.S. Geological Survey details a region where infrastructure is largely dictated by rectilinear monuments. Key thoroughfares such as Lincoln Blvd and Shell Rd traverse the open terrain, providing access to the expansive tracts of t5n r30e and t5n r31e. The presence of Center Monument Line Rd and E Monument Line Rd suggests a landscape heavily managed for boundary precision and resource administration. While the river provides a natural landmark, the human footprint is primarily seen through the geometric precision of routes like Seven Mile Rd.
