National News Release: Study confirms age of oldest fossil human footprints in North America
Two new lines of evidence support the 21,000 to 23,000-year age estimate of the footprints first described and dated in 2021

Snow avalanches are a primary climate-linked driver of mountain ungulate populations
Snow is a major, climate-sensitive feature of the Earth’s surface and catalyst of fundamentally important ecosystem processes. Understanding how snow influences sentinel species in rapidly changing mountain ecosystems is particularly critical. Whereas effects of snow on food availability, energy expenditure, and predation are well documented, we report how avalanches exert major impacts on an ecol
Characterizing vegetation and return periods in avalanche paths using lidar and aerial imagery
Snow avalanches are a hazard and ecological disturbance across mountain landscapes worldwide. Understanding how avalanche frequency affects forests and vegetation improves infrastructure planning, risk management, and avalanche forecasting. We implemented a novel approach using lidar, aerial imagery, and a random forest model to classify imagery-observed vegetation within avalanche paths in southe
Polar paleoenvironmental perspectives on modern climate change
In today’s rapidly changing climate, society needs a better understanding of climate impacts on sea level, ice sheets and glaciers, sea ice, ocean circulation, ecosystems, biodiversity, and other aspects of planet Earth. Paleoenvironmental records provide a unique and invaluable source of insight into these complex issues, and place recent observations into a broader historical context. This essay

Glaciers and Climate Project
Mountain glaciers are dynamic reservoirs of frozen water closely coupled to ecosystems and climate. Glacier change in North America has major socioeconomic impacts, including global sea level change, tourism disruption, natural hazard risk, fishery effects, and water resource alteration. Understanding and quantifying precise connections between glaciers and climate is critical to decision makers...
South Cascade Glacier
South Cascade Glacier is located in the midlatitude maritime climate of the North Cascade Mountains of Washington State. Glacier observations began at this site in 1958.
Lemon Creek Glacier
Lemon Creek Glacier is located in the high-latitude maritime region of Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953.
