1991 Map of Old Man Mountain

USGS Topo · Published 1991

About this map

Old Man Mountain stands as a central landmark within the Los Padres National Forest, marking a landscape defined by dramatic elevation changes along the border of Santa Barbara and Ventura counties. This 1991 survey illustrates the complex drainage systems of the transverse ranges, where Matilija Creek and North Fork Juncal Creek carve through steep canyons. Traces of human activity are concentrated around small outposts like Upper Hartman Ranch and La Carpa Potreros, or the isolated Monte Arido summit. Historical land divisions are preserved in the mapping of the Los Prietos y Najalayegua Grant Boundary, reflecting the region's transition from Spanish land grants to protected federal forest. The map also records essential water sources in this arid environment, including La Carpa Spring and a remote Water Tank located near the peak of Old Man Mountain.
