1981 Map of Granville Canyon

About this map

Granville Canyon and its complex network of drainage systems define the rugged high-country topography of Lincoln County in the early 1980s. The landscape is marked by several named watercourses, including Arroyo Serrano in the north and the winding Agua Chiquita Creek to the south. Small, isolated ranching outposts and named locales such as South Winkler and Pacheco are scattered across the terrain, connected by unimproved roads that navigate the steep elevation changes. The southern portion of the quadrangle is dominated by the confluence of local drainages into Blackwater Canyon, where the Blackwater Ranch represents the primary human footprint in an area otherwise shaped by natural erosion and seasonal flows. This survey provides a clear look at the pastoral and hydrological layout of the region before significant modern development, preserving the locations of rural settlements like Merton.
