View looking downstream at the red sandstone walls of Swallow Canyon. This small canyon is one of two canyons that divide Browns Park into series of intermittent alluvial-meandering and bedrock canyon segments. Unlike Red Canyon and Lodore Canyon, the slope of Swallow Canyon is not controlled by debris flows, and thus does not have any rapids.

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.

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.
