Boyd Spring anchors this high-desert landscape in northeastern Modoc County, where water management is central to the terrain's character. This 2018 survey documents a series of critical upland water sources, including Hawk Reservoir, Level Reservoir, and Boggs Reservoir, which appear alongside natural features like Mud Lake. The western edge of the sheet is defined by the expansive shoreline of Upper Lake, illustrating the drainage patterns of the Surprise Valley region. The geography is marked by seasonal drainages such as First Cr, Second Cr, and Sand Cr, which cut through the topographical relief near Lieberman Canyon. Human impact on the land is represented primarily by utilitarian infrastructure, such as the remote routes Co RD 15 and Co RD 15a, which provide access through the vast public land survey sections.
