Mount Blackburn – Alaska

Mount Blackburn is the tallest peak in the US state of Alaska's Wrangell Mountains. It is the United States' fifth highest peak and North America's twelfth highest point. The mountain is an eroded shield volcano that is the fifth-highest in North America and the second-highest in the United States following Mount Bona. Lt. Henry T. Allen of the United States Army named it after Kentucky senator Joseph Clay Stiles Blackburn in 1885. It's in the center of Wrangell–St. Elias National Park, the country's largest national park.

The massif of the mountain is almost fully covered in icefields and glaciers, and it is the primary source of ice for the Kennicott Glacier, which flows southeast for 20 miles (32 kilometers) until just above McCarthy. The peak also feeds a significant amount of ice to the Kuskulana Glacier system and the north-flowing Nabesna Glacier.
