1948 Map of San Miguel

About this map

The Camp Roberts Military Reservation dominates the western landscape of this 1948 survey, establishing a significant military presence along the Salinas River corridor during the post-war era. The small settlement of San Miguel sits at the southern edge of the quadrangle, serving as a focal point for local commerce and transport where U. S. 101 parallels the Southern Pacific tracks. This transportation spine connects the town with the northern railroad outpost at McKay and the military grounds at Nacimiento. To the east, the terrain rises into the dissected ridges of the Diablo Range, marked by deep drainages like Vineyard Canyon and Mahoney Canyon. The distribution of rural landmarks, such as the Vineyard Sch and various scattered Windmill locations, reflects the region's agricultural reliance on the seasonal flows of Big Sandy Creek and its tributaries.
