Researchers instruct volunteers on how to collect dragonfly larvae in Glacier NP as a part of the Dragonfly Mercury Project.

3D geologic framework model from west-central New Mexico; graphic shows stratigraphic units in the model being sequentially removed to reveal the deeper units. Faults used in the model appear as vertical “ribbons” as geologic layers are removed.

Rhyolite lavas in the Yellowstone Caldera younger than 631,000 years

Map showing ice cover in the Yellowstone region. Light shaded areas bounded by black and red lines indicate areas covered during the Pinedale (about 20,000-15,000 years ago) and Bull Lake (about 150,000 years ago) glaciations, respectively. Blue lines are contours in thousands of feet on the maximum reconstructed Pinedale glacier surface.

RAMPS expands drought adaptation project with national parks in the 4-Corners area. National parks across the desert Southwest are experiencing ecological impacts due to climate change.

Photomicrographs from a Great-Horned Owl showing (A) moderate acute hemorrhage in the right atrial epicardium extending into the myocardium and (B) a focally extensive area of coagulative necrosis of the epidermis and dermis (arrow) consistent with an electrical burn.

RAMPS met with DOI Office of Wildland Fire, US Customs and Border Patrol, and US Fish & Wildlife Service staff at Buenos Aires National Wildlife Refuge in southern AZ last November. The group is developing tools to reduce wildfire risk, conserve wildlife habitat and natural resources, and increase safety and security of border operations.

This huge boulder was dropped by a retreating glacier on the north rim of the Grand Canyon of the Yellowstone in Yellowstone National Park, and it is a testament to Yellowstone's icy past.
