Over Alaska

This travelogue uses helicopter and wildlife photography to capture “the sheer spectacle” of the 49th state. First stop: Mount McKinley (the nation’s tallest), in Denali National Park, where “the laws of nature are strictly enforced,” says narrator Ken Boynton. That’s bad news for salmon, which are seen being eaten by grizzly bears. The hour also visits Anchorage, Skagway, Sitka and the capital, Juneau, but lingers in wilder places.
