1951 Map of North Bloomfield

About this map

San Juan Ridge and its neighboring plateaus define this landscape, where the scars of hydraulic mining remain evident at sites like the Malakoff Diggings. The map captures the complex water management system of the mid-20th century, featuring the Scotts Flat Reservoir and an intricate network of infrastructure including the Blue Ditch, various canals, and flumes designed to move water across the ridgelines. These systems supported both remnant mining operations at the Hoge Mine and Murchie Mine as well as local ranching at Kirkham Ranch and Casci Ranch.
