Intricate erosion of volcanic rock, this mass of volcanic tuff is dissected by rain erosion that consists of numberless spires and pinnacles. It makes picturesque cliffs that are hard to climb. Similar sheets of tuff cover the hills on both sides of Gunnison Valley. Mesa County, Colorado. 1907. Plate 70-B in U.S. Geological Survey. Bulletin 707. 1922.

On May 25th, 2014, a 54.5 Mm3 rock avalanche occurred in the West Salt Creek valley in western Colorado following heavy rainfall on top of snow (Coe and others, 2016a). The data in this project includes boulder density in 20-m x 20-m grid cells for the entire West Salt Creek rock avalanche deposit. The grid cells cover 2,154,800 m2, which accounts for nearly the entire surface of the deposit. We estimated boulder density by counting 1-m or larger diameter boulders of sedimentary rock that are visible in high-resolution Unmanned Aircraft System (UAS) imagery collected for the area in July of 2014 (Coe and others, 2016b). Basalt boulders were excluded from the count because field observations indicated that they generally...

Album caption: Aerial view northeast over the Kahnah Creek embayment and Carson Reservoir. The terminal moraine (tm) left by the Grand Mesa ice can be traced from the main part of Grand Mesa on the left down into the embayment and up onto the Flowing Park Lobe of the mesa on the right. A recessional moriane (rm) produced by a withdrawal of the ice sheet in Grand Mesa time is behind Carson Reservoir. (Graphics on published photograph). n.d. Published as figure 12. U.S. Geological Survey. Professional paper 617.1969.
