1958 Map of Weed

About this map

The Siskiyou Mountains and Marble Mountains dominate this 1950s survey, revealing a landscape defined by massive tectonic uplift and the drainage basins of the Smith River. This compilation by the Army Map Service and U.S. Geological Survey provides a high-altitude perspective on the complex topography of the Pacific Northwest, where the Scott Mountains meet the western edge of the Cascade Range. The map reflects a mid-century period of land management and resource mapping, documenting the extensive network of ridgelines and water systems before modern development altered these remote northern California and southern Oregon corridors. The spatial relationship between these major ranges highlights the region's geological diversity, from the volcanic influence of the Cascades to the ancient metamorphic blocks of the Siskiyous.
