1985 Map of Hillsboro Peak

About this map

Hillsboro Peak dominates this section of the Black Range along the boundary of Grant and Sierra Counties. The landscape is defined by the protected lands of the Gila National Forest and the Aldo Leopold Wilderness, where drainage systems like Gallinas Canyon and North Percha Creek carve deep into the terrain. This 1985 provisional survey captures a transitional moment for the region, documenting a network of pack trails and unimproved roads that provided access for late 20th-century exploration and land management before more modern infrastructure emerged.
