1964 Map of Seep Flat

About this map

Seep Flat and the towering Straight Cliffs dominate this mid-1960s topographic study of the high desert along the border of Garfield and Kane counties. The landscape is defined by the dramatic incision of Right Hand Collet Canyon and Left Hand Collet Canyon, which cut through the uplifted plateaus toward the southeastern drainage of Twentymile Wash. This survey captures the region when its primary human infrastructure consisted of remote livestock facilities like Twentymile Corral and isolated water sources such as Barney Reservoir and Slickrock Water. The mapping of a singular Jeep Trail winding through the terrain suggests the limited accessibility of the era, while the inclusion of the Devils Garden highlights the area's unusual geological formations and erosion patterns.
