1922 Map of Shasta Valley Sheet No 15

About this map

The Klamath River carves a sharp path through the high-elevation terrain of Siskiyou County in this early twentieth-century topographical study. Surveyed by T.H. Moncure in cooperation with the U.S. Reclamation Service, this sheet emphasizes the steep contours and elevation changes that define this river corridor. The presence of specific elevation benchmarks like BM 2113 along the canyon walls indicates the meticulous surveying required for irrigation and water reclamation projects of the era. The mapping reflects a landscape of complex topography where the river is the primary focus, illustrating the challenges of managing water resources in the Klamath-Shasta Valley irrigation district during a period of significant agricultural and engineering development in Northern California.
