Rockies

The Rockies stretch 3,000 miles up the length of North America, and are one of the great mountain ranges of the world. These mountains are home not just to cougars, wolverines, wolves, and grizzly bears, but also daredevil wingsuit flyers, who jump from high peaks, and Native Americans, competing in breakneck horse races.

Jeff Shapiro takes a wingsuit flight in the Bitterroot Mountains, part of the Rocky Mountains.

Oliver Pakootas participates in the Indian Relay and shares the importance of this Native American tradition.

In Wyoming, male bighorn sheep fight head-on in order to mate with females. The noise made by clashing horns can be heard for miles around.
