USGS Scientists Sarah Davis, Taylor Mills, and David Naftz collect soil samples near the Pinenut uranium mine. Mine features visible in the background include the gray ore stockpile at the far left, the head frame used to access the underground mine workings at mid left, and the detention pond containing all water produced on the mine site on the right.

Left Hand Canyon damage by the September 2013 Colorado floodwaters
Left Hand Canyon damage by the September 2013 Colorado floodwatersThe copious rocks carried by the September 2013 Colorado floodwaters pulverized and diluted non-floatable materials from the built environment on the Left Hand Canyon.

While sampling the sediments deposited by the September 2013 Colorado floods, the scientists observed that roads (Left Hand Canyon highway) and houses built on the outside bends of river meanders were particularly vulnerable to flood damages.
