1968 Map of Mt. Harlan

About this map

The Gabilan Range dominates this late-1960s survey, marking the boundary between San Benito and Monterey counties. The landscape is characterized by high peaks and steep canyons, notably Mt Harlan and Bluerock Mtn, which overlook a network of seasonal drainages including Pescadero Creek and Quail Creek. Human presence is sparse, centered on isolated structures like Thompson Cabin and the Rancho Mt Olds to the south. A complex of quarries in the northeast and numerous jeep trails suggest a history of resource extraction and rugged access. The southern portion of the map is defined by the Encinal y Buena Esperanza Grant Bdy, reflecting the enduring legacy of Spanish and Mexican land grants in the California coastal ranges. From the high elevation of Mt Olds to the sheltered Grass Valley, the map details a transitional wilderness between the Salinas Valley and the interior hills.
