The Parting of the Waters, looking southeast. North Two Ocean Creek splits into Atlantic Creek, flowing to the left in the photo, and Pacific Creek, flowing to the right. The wooden sign indicates that it is 3,488 miles to the Atlantic Ocean and 1,353 miles to the Pacific Ocean.

The USGS and partners study the effects of climate change on the Greater Yellowstone Ecosystem. This image shows a research raft on Spider Lake, Wind River Indian Reservation, Wind River Range, Wyoming.

Aerial view of the new thermal area, in the center left. The existing Tern Lake thermal area is the bright white patch of ground in the upper middle part of the image. West Tern Lake is in the lower right. Research conducted under NPS Geology Programs Milestones Permit 2016-9.

View of the Cirque of the Towers in the Wind River Range, with Pingora Peak in the center. The Bull Lake and Pinedale glaciations carved this valley by steepening and smoothing its granite walls. Image captured while descending from Texas Pass. Image view is toward the southwest. USGS photo by Stanley Mordensky, August 2019.

Steamboat Geyser erupts in the golden light of sunrise on July 18th, 2019. The water-dominated part of a Steamboat eruption usually lasts anywhere from 3 to 90 minutes. Afterwards, a steam-dominated phase continues for many hours.

Dead lodgepole pine trees near the parking lot of Fountain Paint Pots in the Lower Geyser Basin. The trees look as if they are wearing white socks; hence, the name, “bobby socks trees.” The dead trees soak up the silica-rich water, turning the lower portion of the trees white.

Images of snow algae and snow cyanobacteria on snow fields in the Beartooth Mountains near the Beartooth Pass Summit (elevation 10,947 ft/3,368 m) on Highway 212. Top left shows a typical pink snow algae bloom on a patch of snow, and top right shows the snow algae bloom scraped off the snow surface with a rock hammer.

Streamflow measurement on Grouse Creek

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.
