Surprise Valley defines this portion of northeastern California, where the expansive bed of Middle Alkali Lake dominates the landscape. The geography is characterized by the fluctuating levels of this terminal lake system, with Hansen Island rising as a distinct landform within the lake bed. Local drainage is marked by seasonal watercourses like Cottonwood Cr and Bull Cr which flow toward the basin floor.
