Most of our views were from the river level, where you are intimately connected to subtleties in flow, wind, and temperature. It was a welcome opportunity to view the river from above and gain context. We stopped here on the last full day on the river.

Anya Metcalf was the insict expert on this trip. We started pointout out and catching bugs for her to identify. This one crawled across camp during our podcast recording. It turned out to be a Golden Stonefly with a small pseudoscoprion attached to the mandlible using the fly for dispersal.

The last night, as we neared Desolation Canyon, the bluffs got taller. Since the Green River is calmer here, it reflected the colors of the sunset. I was so worried about making it before the sun went down that I climbed the peak in my chaco sandals, a decision I regretted the next day since my foot were banged up.

A line of rafts float on flat water with lots of foam. Tan tall cliffs are along the side of the river.

The Green River in the Uinta basin is fairly flat, so it carries a lot of foam. The foam often follows the fastest part of the river, with is ties to the shape of the channel and the curve of the river. From this level, you can sense subltle changes in the plant like, flow speed, temperature, water clarity, and fauna.

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.

We camped on a 20-30 ft. tall hill our last night, so shuttling kitchen gear up and down from the rafts was no easy task.

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.

Early morning panorama of cliffs that signal the start of Desolation Canyon. This was our last, and probably most spectacular, campsite of this section of Uinta Basin. It was approximately 9 miles from our take-out at Sand Wash.

This was our final campsite before we left the river, approximately 9 miles upstream of Sand Wash. The scenery was beginning to transition from the flat and expansive Uinta basin to the high canyon walls that were upcoming in Desolation-Gray.

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.

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.
