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).

Two of the SCREE rafts heading downstream through Swallow Canyon

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.

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.

Andrena spp. seemingly getting a piggyback ride from a bumblebee (Bombus spp.). Researcher was holding the flower on private land in Macon County.

Fruits of Her Labor: the flower on the left has been pollinated and the fruit is developing, but the flower on the right is still being pollinated, highlighting the importance of bees to humanity's food resources. 

The center of the composite flower looks like a "landing zone" and has evolved to guide pollinators to its nectar/pollen.

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.
