At over 2,000 feet deep Black Canyon of the Gunnison National Park has the highest cliffs in Colorado and views of the setting sun to match. The Gunnison River shines at this time of day, like the scales of some ancient serpent, as it winds through one of the steepest canyons in North America. The roaring river gives off 60 decibels below, but from the vertigo-inducing upper rim it seems soft and small, until you remember it was the power that carved the massive natural marvel!
