A USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on Kīlauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by Kīlauea, including sulfur dioxide and carbon dioxide.

A popular hiking trail on the North side of the Anaconda valley in Montana is blanketed in snow.

USGS scientists, working with researchers from the University of Ghent, probed the floor of Eklutna Lake, Anchorage Borough, Alaska, for evidence of turbidity currents triggered by strong shaking during the 2018 Mw7.1 Anchorage earthquake.

A debris flow in Marin County triggered by intense rainfall destroyed several homes and injured one person during February 2019.  View is looking from the top of the landslide downslope.

We are using this piece of equipment to instantly measure stream temperature, pH, dissolved oxygen, and electrical conductivity. When you move the probe up and down in the water column, you can tell if the stream has stratification.

Rain clouds at twilight over the Norhtern Bristol Mountains. THese types of winter storms provide water to the desert ecosystem, but are not usually intense enough to transport sediment or do other geomorphic work.

Areas on Kīlauea that will be covered by a helicopter lidar survey in June 2019. Red lines enclose areas over which the survey helicopter will fly at 396 m (1,300 ft) above ground level. Green lines enclose areas over which the helicopter will fly at 151 m (500 ft) above ground level. USGS map.

After Hurricane Michael obliterated Fish Inn, the sea turtle research team's field station, team members salvaged some of the building's floor tiles and made this sea turtle mosaic, which they plan to eventually install in a new field station.

USGS Hydrologic Technician Chris Broz attempting to find flow at the Rush River at Amenia, ND (USGS streamgage 05060500).  It took the technicians an hour to dig through the snow drift under the wire weight gage just to get to the ice. Then they drilled holes in the ice so they could see if there was any water to measure.

USGS hydrologist Erich Kessler prepares to measure the stream stage (the height of the water surface) of the Middle Fork Crow River near Spice, Minnestota.

Winter fieldwork often requires a few extra steps in gaining access to collection sites. In this image, a USGS employee measures streamflow through holes drilled in the ice using an auger.
