The relationship between Δ30 and N2/3He ratios in hydrothermal gases from Iceland and Yellowstone. Δ30 and N2/3He ratios are shown for samples collected from gases in Iceland (yellow circles) and Yellowstone (red circles). The Yellowstone mantle-endmember is arguably indistinguishable in terms of N2/3He from the convecting upper mantle (grey diamonds).

Researchers Liz Gallegos and Adam Backlin releasing California red-legged frog tadpoles into a temporary enclosure as part of an international translocation. The tadpoles were collected from the Sierra San Pedro Martir mountains of Baja California, Mexico and transported to two sites in the United States.

On April 27, HVO field engineers and a gas geochemist conducted fieldwork to increase HVO's volcano-monitoring capabilities. Staff installed a MultiGAS station to collect volcanic gas data from within Moku‘āweoweo, Mauna Loa's summit caldera. The work was carried out with permission of Hawai‘i Volcanoes National Park.

USGS scientists visit Garden Wall Weather Station in Glacier National Park. This high elevation weather station, just below the Continental Divide near Logan Pass, collects weather data that is used each spring to forecast avalanche hazard for the road crew plowing Going to the Sun Road. The data is also used by USGS avalanche scientists to study the con

With ice off the Wind River near Kinnear, we headed out to make a streamflow measurement in open water. Flows were a bit higher than average for the date (35 years of record) and can be found real-time at: http://ow.ly/eSXS50zcGLF

Scientists with the Interagency Grizzly Bear Study Team have seen the first female grizzly bear with cubs of the year for 2020 in Yellowstone National Park. The radio-collared female was seen with 3 cubs during a telemetry tracking flight on 4/10. One of the 3 cubs is hard to see between the 2 obvious siblings, but you can just make out its
