1953 Map of Placerville

A notable sociological marker is the Iron Springs Mesa School (Aband), reflecting the shifting population of these high-altitude plateaus during the mid-20th century. The intricate network of drainages, such as Sawdust Gulch and Slaughterhouse Gulch, illustrates a terrain shaped by water and rugged enough to isolate early homesteads. Traces of local infrastructure, like a Footbridge across the river at Placerville, highlight the small-scale connections vital to this mining and ranching region.
