Close-up oblique views of Mount Rainier’s west side showing simulated lahar flow depths from a landslide originating in the area of the Tahoma Glacier Headwall (T-260-HM simulation). Imagery appears blurry where lahar material is absent because D-Claw’s adaptive mesh refinement (AMR) employs very coarse resolution in those areas.

High flow on the Elwha River in 2021 at USGS streamgage 12045500. Flooding carried sediment and large wood as well as high volumes of water.

Hydrologic Technician Andy Cripps measures the flow of floodwaters inundating a roadway. The floodwaters occurred in 2021 from a side channel of the Cowlitz River at USGS streamgage 14231000.

Researchers perform gastric lavage on a rainbow trout to sample its stomach contents. This fish was sampled as a part of a food web study on Ross and Diablo Lakes in Washington State to evaluate fish growth and limitations to production.

Locations of barred owl sightings recorded during 2015 owl monitoring activities. Barred owls were lethally removed from the areas highlighted in pink. Supporting data is found at https://doi.org/10.3133/ofr20201089.

Barred owls spread west during the 1900s and today completely overlap the range of the northern spotted owl.

Marshal Hoy, a Biological Science Technician, angling on Ross Lake for Western Fisheries Research Center (WFRC) food web study in October 2021. As a part of this study, fish are sampled for stomach contents, scale samples to assess age and growth, and fin tissue for stable isotopes and genetic analysis.

USGS boat tied to dock at Ross Lake during a week-long sampling trip for a food web study.  Ross Lake is a large reservoir on the Upper Skagit River in the North Cascade mountains of northern Washington state.

Researchers stage sampling equipment at the Ross Lake boat ramp and wait for boat to arrive to transport them to camping area. Food web sampling on large lakes requires a substantial amount of sampling gear. Ross Lake is a large reservoir in the North Cascade mountains of northern Washington state.

Scientists conduct a float survey of the Quillayute River. They measure water temperatures at different depths and locations within the channel along the river's length.
