2023 Map of Chimney Rock

About this map

The Hogback dominates the southeastern quadrant of this San Juan County landscape, marking a sharp geological transition near the settlement of Waterflow. This modern topographic study reveals a complex irrigation network vital to the high desert, including the Hogback Canal, Hogback Canal A Line, and the Jewett-Valley Ditch as they draw from the San Juan River. The terrain is defined by numerous drainage systems such as Eagle Nest Arroyo, Baker Arroyo, and Coal Mine Creek, which carve through the Sand Hills towards the river valley. While recent road infrastructure like Rd 6950 and Indian Svc Rte 38 is present, the map also captures smaller, isolated water features like Chimney Pond and Salt Spring, which have long served as critical landmarks in this arid environment.
