2018 Map of Infernal Caverns

About this map

McArthur sits at the heart of an intricate irrigation network in this Modoc County landscape, where the S Fork Pit River and the Westside Canal facilitate agricultural activity across the valley floor. The map illustrates a highly managed water system, featuring several storage points including McGarva Reservoir and McGarva Reservoir Two in the central hills, alongside Graves Reservoir to the northwest. These resources are critical for a region defined by its seasonal wetlands and springs, such as Sherlock Spring and Wade Williams Spring.
