A raging stream in Rocky Mountain National Park in the Front Range of the spectacular and high Rockies in north-central Colorado. (The towering Front Range is the first mountain range encountered by white settlers years ago, and travelers today, moving west along the 40th parallel north across the Great Plains of North America). The 266,000-acre park is split by the Continental Divide, which gives the eastern and western portions of the park a different character. The east side tends to be drier, with heavily glaciated peaks and cirques. The west side is wetter and more lush, with deep forests. Photo by Carol Highsmith, 2015.
