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.

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.

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.
