A unique cartographic layout highlights the global scope of the US and the associated reach of version 2 of the Cooperative National Geologic Map, which now depicts the history and distribution of geologic units and structures across all states and most territories.

This photo below also shows all the tags that Western Fisheries Research Center scientists use to implant in fish, in reference to a quarter. From top to bottom: quarter, SS300P (depth sensing) acoustic tag, SS400 acoustic tag, ELAT acoustic tag, and a 12mm PIT tag on the bottom.

This is a dredge material deposition site named the Woodland Islands. Western Fisheries Research Center scientists study this area as habitat for fish like salmon.

This is a mountain goat in the upper reach Snake River below Hells Canyon dam and Seven Devils mountains, captured during coop work with Idaho Power by Tobyn Rhodes, a scientist at the Western Fisheries Research Center.

Scientists at the Western Fisheries Research Center collect fish diet samples to analyze their contents and better understand the food web.

This is a photograph of a juvenile Chinook and juvenile Coho salmon fish. Western Fisheries Research Center scientists study these fish.

This is a Lazuli Bunting at Heller Bar boat ramp captured by Rowan Doyle.

Bighorn Lambs and Yews on Cliffs in Middle Reach Below the Salmon River taken by Tobyn Rhodes, Western Fisheries Research Center scientist.

This is a photograph of a Bighorn above Cherry Creek. Alexis Litty took the picture in the fall working on deepwater salmon redd surveys.

This is a photo of a black bear drinking in the upper reach Snake River below Hells Canyon dam and Seven Devils mountains. This photo was shot by Brandon Falish while doing cooperative work with Idaho Power.

Map of the western United States illustrating lands under BLM management as well as locations of Next Generation Weather Surveillance Radars (NEXRAD Stations) and Motus Wildlife Tracking Network stations (Motus Stations) that will be leveraged to understand migratory bird movements and distributions.

This is a photo of scientist, Ramona Rapp, holding a Lost River Sucker that was tagged in Klamath Falls, OR.

This figure shows an approximation of the tectonic plate geometry of western California as it existed roughly 20 million years ago. A piece of the North American tectonic plate has been cut out to show how a slab window is formed when a spreading ridge is subducted.

This is a map of the lower Yakima River showing locations where acoustic telemetry receivers were deployed (open circles) to detect tagged fish that were released at two sites (stars). This was part of the study titled, "Survival implications of diversion entrainment for out-migrating juvenile Chinook Salmon and steelhead.

Chris Pullano and Ryan Tomka load acoustic telemetry receives on to boat in lower Columbia River estuary. Field work was recently completed for the first year of a study to better understand how young salmon use restored habitats in the Lower Columbia River Estuary.

This is a map of the nets on the Upper Klamath Lake in Oregon. The Western Fisheries Research Center carefully monitors juvenile Sucker populations for signs of population recovery and to better understand where they habitate.

Chirs Pullano and Collin Smith unearth the buried cable tethering an acoustic receiver to shore in the lower Columbia River estuary.  Shifting sands frequently bury equipment making it difficult to retrieve. During the 2025 field season, researchers deployed acoustic telemetry equipment to track yearling Chinook salmon as they moved through both restored e

Ryan Tomka retrieves an acoustic telemetry receiver from the lower Columbia River estuary. During the 2025 field season, researchers deployed acoustic telemetry equipment to track yearling Chinook salmon as they moved through both restored estuarine wetlands and the main Columbia River channel.

This is a map of the nets on the Upper Klamath Lake in Oregon. The Western Fisheries Research Center carefully monitors juvenile Sucker populations for signs of population recovery and to better understand where they habitate.

Its early morning as we pass a green expanse of farmland and pull into a parking lot with a boat ramp sloping into the massive waters of Upper Klamath Lake. Paving machines drone next to us, widening the road winding along the lake shore.
