1921 Map of Shasta Valley Sheet No 11

About this map

The Klamath-Shasta Valley Irrigation District and the U.S. Reclamation Service collaborated on this 1921 survey, documenting a landscape at the precipice of major water management changes in Northern California. The terrain is defined by dramatic volcanic features and sharp elevation shifts, most notably the steep rise of the Bluff dominating the eastern portion of the sheet. Local education in this sparsely settled valley centered on the Table Rock School, which sits in the shadow of the prominent rock formations that give the area its character. The map's high-resolution contour lines reflect the intensive engineering focus of the era, as state and federal agencies sought to harness the watershed for agriculture, capturing the intricate natural drainage patterns before modern irrigation infrastructure significantly altered the valley floor.
