1987 Map of Thompson Point

About this map

The Vermilion Cliffs and Shinarump Cliffs dominate this 1987 borderland survey between Kane Co, Utah, and Coconino Co, Arizona. The landscape is defined by massive plateau features like Wygaret Terrace and John R Flat, separated by a complex network of drainages including Hog Canyon and Johnson Wash. A network of 4WD trails provides the only transit through this high-desert terrain, connecting seasonal water sources like Sheep Springs, Willis Spring, and Ram Spring. Evidence of high-altitude industry is present near the southern edge of the sheet, where Open Pit Mines are situated within Eightmile Gap. Notable topographic landmarks such as Thompson Point and Savage Point overlook deep canyons and coves, illustrating the stark erosion patterns characteristic of the Colorado Plateau.
