USGS scientists Rebecca Kramer and Dan Dzurisin install a solar panel and GPS antenna (green square) at a semipermanent GPS station in the southern part of Yellowstone National Park. The work first required digging through 4 feet of snow!

During the lidar survey, equipment will be mounted on a bright yellow Hughes 500 helicopter like the one shown here. The helicopter will fly in a northeast or southwest direction over the survey areas depicted on the map.

With the help of a powerful telephoto lens, HVO geologists confirmed today that there are two areas of ponded water at the bottom of Halema‘uma‘u. Using a laser range finder from their observation site, they were able to measure the two greenish ponds.

This image shows an area of greenish fume (near top of photo) east of the water pond (center) at the bottom of Halema‘uma‘u. This fume could suggest another emerging area of ponded water, but this has not yet been confirmed. HVO continues to closely monitor the area, and will report any significant changes.

While making observations today, HVO geologists noted a koa‘e kea (white-tailed tropicbird) gliding across the ponded water at the bottom of Halema‘uma‘u. The bird is visible in the top left quarter of the photo. USGS photo by M. Patrick, 08/03/2019.
