The namesake of the City of Steamboat Springs was once a geyser. Now the spring upwells into a large pool before flowing out to the Yampa River.

Mineral production lifecycle from exploration through reclamation.

Artistic rendition of the mineral lifecycle from a natural state through to exploration, permitting, mining, and reclamation. Designed for the Minerals Lifecycle Integrated Science Team to depict one aspect of their science focus.

USGS hydrologists use thermal infrared (IR) imagery to evaluate the distribution of warm and hot springs near the Yampa River. Numerous diffuse springs discharge near the river, and IR imagery is useful as a screening tool to pinpoint points of discharge to be sampled for water quality.

Geothermal groundwater discharge is a substantial source of salinity to the Colorado River. USGS scientists sample geothermal springs to learn more about the age of groundwater and the rock units that interact with groundwater.

This image shows the Blue Ridge Meteorological Station after installation before snow accumulation.  The image is useful to see the station structure and layout of installed sensors as well as the limited snow cover common in the early and late seasons.

USGS scientists injected a non-toxic fluorescent dye into the Slate River to identify zones of groundwater discharge.

Rain Gauge installed after the 2020 Grizzly Creek fire in Glenwood Canyon, Colorado. Scientists installed a network of rain gauges and soil moisture sensors throughout the rugged burn area. These instruments provide real-time data on rainfall intensity and duration, which are critical factors in determining the likelihood of a debris flow.
