1952 Map of San Luis Obispo

About this map

San Luis Obispo sits at the heart of this mid-century coastal valley, showing the city's early footprint around landmarks like California State Polytechnic College and the local High Sch and Junior College. The landscape is defined by the steep grades of Cuesta Pass, where the Southern Pacific railroad and highway navigate the sharp transition between the coastal plain and the inland hills. To the north, the planned community of Atascadero and the village of Santa Margarita mark the upper reaches of the Salinas River drainage.
