Winter visitors to Denali National Park are sometimes treated to a viewing of the aurora borealis, or northern lights, seen here beaming down above the Chugach Mountains south of the park.
If you're looking for whales and waterfalls, blue glaciers and sharp-toothed mountains, there's enough visual overload here to fill a hard drive with digital pictures.
Denali’s paths all lead visitors through its majestic valleys toward the towering Mount McKinley, the crown jewel of the park. On clear days, McKinley can be seen 70 miles (113 kilometers) to the southwest.
Take a visual journey to Alaska, where huge Kodiak brown bears roam freely, the seas and streams teem with salmon, and the lush landscape is more than just a backdrop.
