Rigging the boats on chilly desert mornings is a slow affair. All our food and gear must be sorted, distributed and carefully packed among the six rafts to be able to accommodate its passengers and so it can all be easily found again when we reach our evening camp.

Scientist on boat examines a large piece of driftwood
Sampling pre-emergent aquatic insects is not always easy, especially on a river with little cobble substrate. Because of the high water from dam release, a lot of floating driftwood was making its way down river. We are testing a new method to sample this substrate for benthic invertebrates to examine questions of species diversity, dispersal and habitat use.

After a mid-morning launch, Team D floats south from Split Mtn
In high-flow conditions, Team D took off from Split Mountain campground in 6 rafts. Split Mountain is shown in the background.

A scientist is scooping up sand near the river bank.
The sediment sampling project was intended to provide insight into the presence of microplastics in the Colorado River basin. Samples were collected at every campsite that had an adequate supply of sand.

For Team D, this was our first morning on the river, putting-in at Split Mountain campground in Dinosaur Nat'l Monument. The whole group was very excited as none of the expedition members had ever rafted this section of the Green River.

Public Outreach event at Split Mountain Campground
There was an educational outreach event to describe the fish conservation and Powell expedition involving SCREE and Bureau of Reclamation.

Split Mountain - a very large rock.
Split Mountain Campground was the beginning of our jouney. We met up with the SCREE expedition in this cozy spot tucked beneath the imposing Split Mountains.

The Green River traces its course through the desert.
Looking at the route we would be taking the next day, we pondered what lay ahead. Vast, open country and lots of rocks were in our future.

Tom, Tildon Jones (USFWS), and Jim Prairie (BoR)
Tom, Tildon Jones (USFWS), and Jim Prairie (BoR) present at the Green River Campground for an "evening program" at Dinosaur National Monument. Many campers were in attendance, as were several deer across the river.

The Uinta Basin represents an area of high productivity for agriculture, ranching and fossil fuel exploration. Recreational activities such as rafting share this landscape with wildlife and industry.

Yellow SCREE expedition raft in Browns Park, Green River.
The yellow raft of SCREE expedition leader, Tom Minckley, floating through calm waters of Browns Park National Wildlife Refuge, Colorado. The far bank in the midground of the photo are the exposed sediments of the pre-dam floodplain of the Green River. The layers of rock in the background are the exposed layers of the red Uinta Mountain Group quartzite.

A meander in the Green River at Brown's Park
A view looking down on the river from the hills above camp. View is upstream and shows a nice river meander with a point bar and scenic hills in the background. This is in Brown's Park.

Gates of Lodore looming from Brown's Park
The scenic view of the Gates of Lodore from Brown's Park. The Green River through Brown's Park is very calm, slow moving water, with canyon walls and up ahead looms the scar where the river has eroded it's way down through the mountains.
