USGS employee Joe Adams positions a UAS over a calibration panel to capture a multispectral image with the attached MicaSense Dual multispectral sensor. This calibration image will be used to post-process the imagery in support of radiometric calibration research conducted at the Denver Federal Center in Colorado.

Research Geologist Natalie Kehrwald cuts a “cookie” from a fire-scarred tree in the southern Sangre de Cristo Mountains, New Mexico. Cookies are cross-sections of trees that provide information on the interactions between past droughts and fires.

High altitude lakes provide opportunities to examine interactions between fires, drought and human activity across decadal to millennial timescales. The locations of these lakes near tree line make them more susceptible to climate-related changes in vegetation and associated biomass burning.

Perspective view of the Continental U.S. showing an elevation surface of the top of crystalline Precambrian “basement” rocks. Brown and orange colors depict the highest elevations; greens show the lowest elevations. Surface is incomplete in the western U.S. where there are no published “basement” maps or where crystalline Precambrian rocks are not present.
