Overlooking SCREE's fourth camp
Overlooking SCREE's fourth camp, on the shore of Flaming Gorge Reservoir just above the Flaming Gorge Dam. The five SCREE boats as well as University of Wyoming's research vessel can be seen beached on a narrow band of sand and rocks just below a steep forested hillside. (May 27th, 2019.)

Beach on Flaming Gorge Reservoir
On the expedition, USGS scientists are tasked with collecting sediment samples from the beaches where we camp. The goal of the study is to examine the presence of microplastics along the river. There are strict protocols on the condition of the sediment we collect, so sometimes we have to travel far from camp in order to find suitable sediment.

Overlooking SCREE's third camp, on the shore of Flaming Gorge Reservoir. In addition to the 5 SCREE boats, the University of Wyoming research vessel that towed the Expedition down 70 miles of man-made lake is beached for the evening. Tents have been set up for the night, and dinner is being prepared (May 26th, 2019).

Paper Powell with Sagebrush desert in background
Paper Powell! Behind him is a sagebrush steppe environment. Sagebrush steppe is a type of ecosystem strongly characterized by the presence of sagebrush species, particularly Big Sagebrush, or Artemisia tridentata. Sagebrush steppe today is threatened by many factors, including the presence of invasive species.
