1971 Map of Sunstone Knoll

About this map

Sunstone Knoll rises above the basin floor in this 1971 survey of Millard County, marking a stark volcanic landmark in a landscape defined by the remnants of prehistoric water systems. The Union Pacific line cuts a straight northeast-southwest path across the terrain, passing through the small outpost at Van and skirting the edge of the vast Mud Depression. This arid basin features the meandering path of the Old Sevier River Channel, which illustrates the shifting drainage patterns of the desert. To the west, the dark volcanic flows of Black Rock and the distinct profile of the Great Stone Face provide rugged topographical contrast to the low-lying wetlands. The southern reaches of the map are dominated by the Clear Lake Waterfowl Management Area, where the presence of a Borrow Pit and a Prospect indicate localized efforts to extract materials from the volcanic and alluvial deposits.
