Three boats make their way around the bend near Dinosaur National Monument while the jagged edges of Split Mountain tower in the background.

Tom Minckley and Nick Hammond study the shore for plant and animal species and to enjoy the beautiful landscapes as they pass by.

As Split Mountain slowly retreats from view, expedition leader Tom Minckley and Jaime Delano make their way steadily down river.

Pat Kikut and Graham Lederer move quietly by the beautiful geologic formations along the Green River.

In the desert, mother nature provides us with curved and sharp edged shapes, thorns and soft cottonny seeds, as well as brilliant and subdued colors side by side. The desert seems to have a bit of everything.

While the lavendar color of the Tamarisk plant is nice to see, the plant is actually an invasive species. The Tamarisk Beatle was released in 2005 to combat the spread of the plant and has been quite successful in doing so.

Mitch Eaton attempts some fly fishing ultimately to no avail while Austin Alvarado looks on. As with the original 1869 Powell expedition, catching fish in the Green River is not an easily acocmplished endeavor.

Tom McKinley was able to answer many of our questions about plant names and ecology in the area. When I shared his boat on the second day, he told me that the orange Globe Mallow flowers close up at night. Solitary bees will hold the stamen and let the flow close around them, using the flower for warmth and protection.

Our first day was full of uncertainty about what we would experience. Many of us did not have experience on the river (although Anya Metcalf, in the photo, did). We left the impressive cliffs and topography of Split mountain wihout knowing what lay ahead, expecting less exciting topography, but we were all proven wrong about the Uinta basin.

Most of our days had this view- looking back on the river and having conversations with the rafter rowing the boat and whomever else we shared space. We were constantly surprised at the beautiful views and the impressive cliffs, which often housed cliff swallows.

One of the topics we frequently talked about was land use. The Green River in the Uinta is different from other segments because it is surrounded by industrial activity, with scattered farms, livestock, oil pumpjacks. It is not known as a recreational destination, although the beauty is overlooked.

These lands have never been empty, although in some places it feels that way. Before western settlers arrived, these lands were polulated by other peoples throughout prehistory. Tom McKinley estimates that these images were drawn during the Fremont age. Some images are clearly human, one may be a fish, others are less clear.
