Boulders of Snow
Black Canyon of the Gunnison National Park, Colorado, 2014
The Black Canyon of the Gunnison River is spectacularly beautiful any time of year, but winter may be the best time to explore it. This and other viewpoints along the south rim are accessible in winter by skiing or snowshoeing the road. In this image, several inches of new snow round off the jagged edges of Black Canyon's Precambrian rocks. Photo © copyright by Greg Owens.
