Skinney Rock stands as a prominent landmark in this high-desert landscape where the border between San Juan County and Colorado meets. The terrain is defined by volcanic features and distinct elevations such as Volcano Peak, Black Cone, and the broad plateau of Flat Top Rock. These geological formations are intersected by a network of seasonal watercourses, including Malpais Arroyo and Salt Creek Wash, which drain the arid reaches of the San Juan Basin.
