About this map

Fall River meanders through a complex valley landscape of volcanic formations and marshy lowlands in this early 1960s study of northeast California. The convergence of the Fall River and the Pit River at Fall River Mills anchors a region defined by extensive water management, visible through the McArthur Diversion Canal and the Lee Drainage Canal. These engineering works transformed the McArthur Swamp and surrounding areas, supporting agricultural settlements like McArthur and Pittville.

The terrain shifts dramatically from the aquatic environments of Big Lake and Horr Pond to the arid elevations of the Big Valley Mountains and the volcanic Lava Beds. Distinctive landmarks such as Timbered Crater and Widow Mtn provide significant vertical relief against the valley floor. For genealogists and local historians, the map preserves the locations of rural infrastructure, including Island School, the Intermountain Fairgrounds, and several remote outposts like Brown Cabin and the Wiley Ranch Guard Station.
