Denali National Park in Alaska is six million acres of wild land, bisected by one ribbon of road. Travelers along the road see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America’s tallest peak. Called The Mountain by locals, Denali stands 20,310 feet tall. Photo by National Park Service. Posted on Tumblr by the US Department of the Interior, 12/10/16.
