2021 Map of Hansen Island

USGS Topo · Published 2021

About this map

Middle Alkali Lake dominates this portion of the Surprise Valley floor, where the seasonal waters of the high desert basin meet the land at Hansen Island. The landscape is defined by the hydrologic patterns of the Great Basin, with drainage features such as Cottonwood Cr, Little Cottonwood Cr, and Bull Cr leading toward the lake bed. A sparse network of local thoroughfares, including Patterson Ln and various county roads like Co RD 30 and Co RD 31, provide the primary access to the scattered landholdings in this Modoc County interior. This 2021 update maintains the public land survey system grid, showing the township and range divisions that have organized this remote northern California territory for over a century.
