About this map

Irish Hill and the surrounding Amador County landscape are defined by a complex network of resource extraction and water management in the early 1960s. The terrain is marked by numerous industrial signatures, from the Claypit and Gravel Pit workings near Edwin to the Tailings and various Prospect sites scattered across the hills. The Southern Pacific railroad line cuts through the southwest corner, providing a vital link for the region's mineral and clay output.

Water distribution is central to this environment, evidenced by the Michigan Bar Ditch and Willow Springs, alongside man-made features like Henderson Reservoir and the Gaging Station on Dry Creek. Educational and social history is anchored by the Willow Springs Sch, while the presence of Ruins and a Cem near the center of the map suggests earlier layers of settlement that predated this mid-century survey. The topography rises sharply at Sugarloaf Peak and Bisbee Peak, overlooking a landscape still actively shaped by the Arroyo Seco drainage system.
