View to the southeast from near the Canning River Delta. Visible in foreground are permafrost polygons cut by caribou trails.

View to northeast from southwestern 1002 Area with ice in Camden Bay in distance. In foreground, red-weathering rocks are Hue Shale (oil-prone source rock with is present throughout 1002 Area) and dark gray rocks are Kemik Sandstone (lateral equivalent to Thomson sandstone, main reservoir in Pt. Thomson field).

Did you know fossil pollen and spores can help us understand past climate variability?

You are looking at microscopic images of ~55-million-year old pollen grains and spores that were isolated from a geologic unit known as the Marlboro Clay in Maryland. The presence of plant groups now found in tropical, subtropical, and temperate areas indicate that climates were

The CMHRP has been conducting scientific investigations at Fire Island in order to protect natural and cultural resources.

Congratulations to Dr. Anne Wein, Operations Research Analyst at WGSC, who received a 2019 Bay Area Metro Award from the Association of Bay Area Governments and the Metropolitan Transportation Commission for her work as lead researcher for the HayWired earthquake scenario. The HayWired Scenario is a 4-year scientific analysis to anticipate the potential impacts of a 7.0

Florence Bascom joins John Wesley Powell on a 5-day leg of the Powell 150 Expedition, marking the 150th anniversary of the Powell Expedition, an exploration of the Green and Colorado Rivers that ended in the Grand Canyon. The purpose of the Powell 150 Expedition is to inform and engage the public around the geology and ecology of rivers in general and this river system in
