1983 Map of Grindstone

In the early 1980s, the rural character of the region remained firmly intact, anchored by landmarks such as Lincoln Sch in the northern portion of the quadrangle. The map captures the scattered nature of habitation, with Poeno situated along the lower reaches of the river system. This survey provides a clear view of the section lines and township boundaries that organized the western prairie, documenting the specific locations of remote schools and namesake creeks that may have shifted or faded in the decades since the field check.
