2018 Map of Hansen Island

About this map

Middle Alkali Lake dominates this portion of the Surprise Valley, revealing a landscape defined by the seasonal ebbs and flows of a high-desert basin. The eastern shore of the lakebed is fed by watercourses like Bull Cr, while the western edge transitions into land marked by early township boundaries. Hansen Island stands out as a distinct landform within the lake's footprint, appearing here alongside the Outlet to the south. Local transit is managed by a network of rural routes, including Co Rd 30 and Patterson Ln, which provide access to the agricultural and grazing tracts bordering Cottonwood Cr. This survey illustrates the relationship between the arid alkali flats and the persistent water sources that supported settlement in Modoc County during the early 21st century.
