Alaska is known as the "last frontier" with long summer days and gigantic flowers. Typical homes in Fairbanks have heavy logs and multiple paned windows. Most travel is by small private aircraft or boats along rivers and pipelines carry oil above the frozen ground. Visitors can see Denali National Park by helicopter or luxury train and its blue glaciers formed under pressure over thousands of years. Southeast Alaska has many communities connected by water and ferries, with towns like Skagway and Sitka showcasing Native culture through totem poles and dance despite Russian Orthodox influence. Wildlife like eagles, whales, and salmon are prevalent in the rugged coastal landscape.
