Painted Wall, Sunrise
Black Canyon of the Gunnison National Park, Colorado, 2014
In a state known for its 14ers, the Painted Wall of Black Canyon is Colorado's tallest sheer wall with a vertical relief of 2250 feet. The lighter streaks across its face are composed of pegmatite, a mineral characterized by relatively large crystals that often contain lithium and boron. Or perhaps the streaks are scratches left by the claws of an ancient dragon. Maybe Smaug. Photo © copyright by Greg Owens.
