About this map

Jamul and North Jamul anchor the northwestern portion of this San Diego County quadrangle, showing a landscape defined by ranching and rugged canyons before late-century suburbanization. The terrain is marked by steep elevation changes from McGinty Mountain and Lyons Peak down into valleys like Lee Valley and Lawson Valley. Local infrastructure of the era includes the Jamul Las Flores Sch and St Francis Xavier Cem, alongside scattered agricultural holdings like Mountain Shadows Ranch and the Skyline Ranch.

Resource extraction and transit routes are well-documented, with the Peg Leg Mine and various Prospects noted in the high country. In the southeast, Dulzura and Engineer Springs sit along the winding canyon roads, where the Dulzura Creek and Sycamore Canyon drainage systems converge. Significant portions of the eastern and southern map are preserved within the Cleveland National Forest and the Otay National Cooperative Land and Wildlife Management Area, highlighting the region's long-standing transition between private ranchland and public wilderness.
