About this map

Alturas serves as the focal point of this 1990 survey, situated at the confluence where the Pit River meets its north and south forks. The town's civic infrastructure is well-defined, showing the Modoc High Sch, Warner High Sch, and the Municipal Airport alongside the Alturas Rancheria to the east. The map captures a high desert landscape shaped by water management and conservation, with the Modoc National Wildlife Refuge dominating the wetlands south of the city center.

Evidence of local industry and agriculture appears through numerous irrigation features like the Woods Place Dam and various borrow pits and wells. The terrain transitions from the river valley floor to distinctive volcanic-like formations such as The Three Sisters, The Hat, and Signal Butte. Small outlying settlements and transit points, including Juniper and Lakeview Junction, provide a clear picture of the region's distribution and connectivity during the late 20th century.
