Red rock formations rise from the surrounding landscape, remnants of ancient geological forces that carved Flaming Gorge. The reservoir's blue-green water sits within reach, reflecting the sky and canyon walls. At this elevation, meadow grasses fill open spaces between trees, and wildflowers peak in summer months.
