On our last day of the expedition the landscape was dominated by the Green River Formation, famous for its fish fossils (although none were found in camp).

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.

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.

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.

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.

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.

Team D enters the middle of the Uinta basin on Day 2, with Split Mountain still visible. The flow of the river greatly increased that day due to a controlled release at Flaming Gorge Dam. The high flow is meant to carry the larvae of an endangered species of sucker fish into bordering wetlands, where the larvae can grow under more protected conditions.

One of the ongoing experiments on the expedition is a bioacoustic survey monitor, which will parse recorded nighttime sounds into species and numbers of individuals. Here Tom Minckley explains it to USGS scientists Mitch Eaton, Jamie Delano, and John Parks.

Ben Capelin and Austin Alvarado have multi-faceted roles on the expedition, serving as expert boatmen, talented cooks, evening companions, and contributors to any discussions.

In high-flow conditions, Team D took off from Split Mountain campground in 6 rafts. Split Mountain is shown in the background.
