About this map

Simi Valley is shown during a transformative mid-century period, capturing the landscape as it shifted from a rural agricultural basin into an expanding residential and educational hub. The valley floor is bisected by the Southern Pacific railroad and the Arroyo Simi, with early developments like Virginia Colony and Strathearn providing a look at the area's older settlement patterns. Higher education and local community growth are anchored by Moorpark College and several local institutions like Royal High Sch and Sinaloa Jr High Sch.

To the north, the terrain rises sharply into the Oak Ridge and Big Mountain ranges, where more isolated features like Happy Camp and numerous Wells and Springs reflect a different, more resource-focused use of the land. Evidence of early entertainment and transit infrastructure appears through the inclusion of a Drive-in Theater and a Landing Field, while industrial activity is noted at the Quarry and various gravel pits.
