About this map

The Santa Ana River carves a central path through this Southern California landscape, flowing from the Canyon de Santa Ana toward the coastal plains. At the turn of the century, the region was defined by a complex network of irrigation and industry, seen in the Yorba Canal and California Canal that supported the emerging agricultural centers of Anaheim, Orange, and Fullerton. While the valleys were beginning to fill with settlements like Placentia and Garden Grove, the eastern reaches remained dominated by the high peaks of the Trabuco Canyon Forest Reserve. Here, extractive industry left its mark with the Santiago Coal Mine and another Coal Mine situated along the slopes. To the west, the Southern Pacific R.R. connects coastal towns like Newport Beach to the interior, passing through the ranching lands of the San Joaquin Hills and the sprawling Las Bolsas territory.
