Santa Ysabel and the surrounding highlands of the Cleveland National Forest define this 1960 landscape, showing a transition from ranching valleys to rugged mountain terrain. The map captures established rural life at the Spencer Valley Sch and Santa Ysabel Sch, while tracing the local mining history through the Old Virginia Mine and the Pride of the West Mine. The presence of the Santa Ysabel Indian Res and Inaja Indian Reservation highlights the complex land use and heritage of the region during the mid-20th century. High elevations like Witch Creek Mtn overlook numerous named flats and canyons, including Daley Flat and Dye Canyon. The headwaters of the San Diego River and Santa Ysabel Creek provide the primary drainage for this backcountry area, which was updated in 1982 to reflect more recent aerial photography.
