Landform
A Chugwater red-bed canyon cut into the Wind River foothills. Orange and scarlet cliffs above a grass valley, snow-lined in winter.
Field note
The Chugwater Formation is Wyoming’s warmest color. From the overlook the canyon runs like a wound through the hills. After a storm the red beds show through the snow. The Wind Rivers stand west when the air is clear.
