A great examples of the crossbeds in the Uinta Formation, a quarzite dating back to the PreCambrian, on a beautiful sunny morning with mist hanging above the river as the sun rises.

View looking upstream from a raft on the Green River at the downstream end of Swinging Bridge Canyon, near Flynn Bottom. The eastern end of the Unita Mountains lie in the background. A pump station supplying water to the flooded wetlands of Brown's Park National Wildlife Refuge can be seen on the right near the edge of water.

View looking at a shallow side channel of the Green River in Brown's Park, Colorado. The picture is taken looking downstream from the left bank of the river. In the foreground and on the opposite bank are stands of sandbar willow (Salix exigua). Further beyond, are stands of Fremont cottonwood (Populus fremontii).

The photo shows the SCREE Powell 150 expdition camp at Big Pine Campground in Red Canyon of the Green River, Utah. The large green tarp was set up to keep the kitchen area and campers dry. Two very large ponderosa pines are in the center of camp, and surely were witness to the 1869 Powell expedition.

This photo displays the contrast between the clear, sediment-starved waters released from a large dam, and the murky, sediment-rich waters of natural tributaries. The tributary is just one of many that gradually re-supply the river with sediment.

This photo demonstrates one of the challenges of down-river boating in the Colorado River system.

This photo demonstrates the typical set up of the so-called 'bat-and-bug' citizen science data collection platform used on the SCREE - Powell 150 expedition. The UV light attracts bugs to the pool of ethanol, where they land and are preserved for identification, while the touchpad device has an untrasonic microphone to collect bat calls.

Desert paintbrush stands out against the yellows and browns of the desert by way of its bright red and fiery coloring. Desert paintbrush is a hemiparasite, and takes some of its water and nutrients from the roots of nearby plants. However, unlike full parasites, desert paintbrush can still photosynthesize to obtain some of its nutrients if needed.
