The Green River and Colorado River meet in a dramatic confluence recorded here during the early 1950s. This survey, mapped by the Geological Survey using aerial photography, documents the deep vertical relief where the rivers carve into the plateau. The terrain is characterized by massive formations like Petes Mesa and the spire-like landmarks of Candlestick Spire, Standing Rock, and Lizard Rock. Below the confluence, the combined waters enter Cataract Canyon at Spanish Bottom, a significant geographic point for river navigation and geological study. The map also reveals a complex network of dry washes and deep fissures, including Twin Canyon and Cyclone Canyon, alongside the expansive grazing surfaces of North Flat and Erman Flat.
