The Santa Ana River carves through this Southern California landscape at the turn of the century, serving as the vital lifeline for a burgeoning citrus and agricultural empire. The map reveals the early irrigation infrastructure critical to the region's development, notably the Anaheim and Santa Ana Canal and several smaller canal networks branching off near Yorba. The surveyor E.G. Hamilton revised the cultural features just as the rail-and-river economy was maturing, showing a dense grid of developing townsites like Anaheim, Orange, and Fullerton linked by the Southern California R. R. and the Southern Pacific R. R.
