USGS scientists dig small ‘micro pits' to collect soil for testing. The team is careful to minimize the impact to the environment. Soil is stored on a tarp while sampling so it can be returned to the pit afterwards.

A USGS scientist prepares a mini-disc infiltrometer to assess soil water infiltration. The degree to which water can infiltrate soil is closely tied to soil carbon content.

A USGS scientist uses the grid-point intercept method to characterize plant communities in Larimer County, Colorado. The grid-point intercept method uses points along a grid to sample plant species or ground cover within a larger plot.

In streams affected by acid mine drainage, inflows of diffuse groundwater (nearly invisible to the eye) can substantially control metal mobility, such as in this photo where copper minerals are precipitating along a reach of stream where groundwater with a distinctive composition flows into the stream. 

Mineral precipitates in mine tunnels, such as the copper-rich minerals in this mine in Oregon, may provide information on the paths of groundwater that discharge into the tunnels, informing strategies for metal recovery and potential remediation.

Montana is known for its fishing opportunities, especially its cold-water trout fishing. Here, someone is fishing in Big Hole River, Montana. 

The Ruby River is a tributary of the Beaverhead River and anglers enjoy trout fishing here.
