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! 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.

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.

Waking up in the early morning revealed a layer of fog that had fallen around our camp and the river. Fog is the result of water vapor condensing into water droplets that are suspended the air.

Preparing for Launch

Launch day is a busy but exciting day for all SCREE participants, and in this photo, several members can be seen loading gear onto the rafts and making sure they are prepared. A 70-day expedition requires quite a bit of important equipment and rations, so the rafts are loaded with the appropriate items, and the inventory triple-checked.
