The final morning view from my text as the sun rose from the east and illuminated cliffs on the west. This trip was so wonderful and exceeded all of our expectations, it was hard to go back to reality.

Lukas Winkler-Prins checks on the frame setup on June 10, 2019.  This tripod has an RBR CTD, an RBR bursting pressure sensor, an RBR optical backscatter sensor, a LISST-200X, an altimeter, and two Nortek ADVs + Seapoint optical backscatter sensors, which will reveal information about water temperature and salinity, wave height and period, total s

Although we were all hoping it would never end, the final day on the river was a bittersweet reminder of the amazing experiences we had in the Uinta Basin.

During field observations on August 8, HVO scientists noted that all three ponds are now joined, indicating that the water at the bottom of Halema‘uma‘u continues to slowly rise. Rangefinder measurements also suggested continued pond deepening.

Morning on the Green River (Uinta Basin) for the celebratory and re-envisioning expedition honoring the 150 year anniversary of JW Powell’s exploration of the Colorado Plateau, summer 2019.  Eaton was selected by USGS’s Youth and Education in Science (YES) to participate in this USGS and University of Wyoming

Although this section of the Green River in the Uinta basin lies between sections of dramatic red-stone cliffs of Ladore and Desolation Canyons, we did experience some profound geology. These cliffs are near the start of Desolation Canyon to the south.

An integral part of each segment of the expedition is a recorded dialogue in which participans reflect on such things as Powell's legacy, the future of the West in light of water and energy issues, and what personal growth has occurred as a result of the expedition.

This calm section of river flows through a National Wildlife Refuge where we observed a great deal of wildlife, including beaver, peregrin falcons, waterfowl, a coyote, bighorn sheep and American white pelicans

USGS geologist Graham Lederer (L) wrote a song about the expedition while floating down the river, and Professor Pat Likut (R), who teaches art at the University of Wyoming, did landscape sketches that he will later turn into oil paintings.

Starting two years ago, Professor Tom Minckley, from the University of Wyoming geology department, conceived and organized the Sesquicentennial Colorado River Exploring Expedition (SCREE), also known as the Powell 150 expedition. The USGS joined as a partner last year.

On a calm river with no rapids or impediments, boaters often tie up rafts together in a flotilla or 'party barge' to socialize, share snacks or just enjoy the scenery with a group

University of Wyoming grad student (media and communications) Ben Kraushaar is also an accomplished filmmaker, and is making a film of the expedition using both eyelevel shots and lofty drone aerials. He was instrumental in getting equipment of all types donated to the expedition.

The brick-red, flat-lying Duchesne Formation sandstones dominated the landscape for a couple days. Its bluffs are a favorite nesting spot for cliff swallows, of which we saw many, and peregrine falcons, of which we saw two.
