1974 Map of Yreka NW

About this map

The northern edge of Yreka dominates the northeastern corner of this 1974 orthophotoquad, where the city’s grid meets the foothills of Siskiyou County. This aerial perspective shows the transition from urban development and the primary highway corridor to the varied terrain of the Klamath Mountains. Waterways like Yreka Creek and Moffett Creek dictate the layout of roads and agricultural clearings, while high points such as Manzanita Hill overlook the narrow valleys. Unlike traditional topographic maps, this imagery-based study reveals the exact vegetation patterns and land-use boundaries in the mid-1970s, providing a clear visual record of how the community occupied the floor of the Shasta Valley before modern expansion further altered the surrounding slopes.
