About this map

Mallagh Landing and the rugged coastline of San Luis Obispo Bay define this late 19th-century coastal landscape. The region's early industrial and recreational roots are visible in the Asphalt Mines near Edna and the therapeutic destination of Newsom Springs. Two major rail lines, the Southern Pacific R. R. and the Pacific Coast R. R., intersect the terrain, connecting coastal settlements like Pismo and Oceano to the interior valleys.

Inland, the Arroyo Grande Valley is framed by the San Luis Range and Santa Manuela hills. The map details a complex drainage system including Pismo Creek and Arroyo Grande Creek, which feed into coastal lagoons such as Pismo Lake and Oso Flaco Lake. This survey preserves the exact locations of early landings and vanished stations like Steele and Maxwellton before the expansion of modern Central Coast infrastructure.
