1980 Map of Seiad Valley

USGS Topo · Published 1988

About this map

Seiad Valley sits along a northern bend of the Klamath River, serving as a central point of settlement in this remote Siskiyou County landscape. The mapping, based on 1972 aerial photography and 1974 field checks, reveals a topography defined by the confluence of major drainages and agricultural activity at the Grider Creek Ranch. The river dominates the valley floor, fed by significant tributaries like Grider Creek and the East Fork Seiad Creek, which carve through the surrounding high ridges of the Klamath National Forest. This 1980 edition provides a clear record of the small-scale ranching and rural infrastructure that sustained this northern California community in the mid-1970s, before later environmental or land-use changes.
