Ben Glass of the USGS Colorado Water Science Center collects streamflow data from a USGS rapid deployment streamgage on the Big Thompson River in Loveland, Colo. The river is one of many that flooded during a significant September 2013 rain event along Colorado's Front Range, damaging or destroying several USGS streamgages.

Bob Brandle and Cory Stevens of the USGS Colorado Water Science Center record streamflow and water level measurements for the flooded St. Vrain River near Longmont, Colo. The river is one of many that flooded during a significant September 2013 rain event along Colorado's Front Range, damaging or destroying several USGS streamgages.

When looking for a place to set up a capture location, biologists look for existing bear sign such as scratches on trees and bear scat.  Sometimes traps are set in areas that have no obvious bear sign to determine if indeed bears are present.

Oilfield waste arrives by tanker truck at a wastewater disposal facility near Platteville, Colo. After removal of solids and oil, the wastewater is injected into a deep well for permanent storage underground. This disposal process has the potential to trigger earthquakes, but very few wastewater disposal wells produce earthquakes.
