Mount Blackburn / K’a’si Tl’aadi
Language: Ahtna
Meaning: The one at cold headwaters. (Literal)
Volcanic Province: Wrangell Volcanic Arc
Location: Ahtna Nenn’ / East-Central Alaska, USA
Type: Scientists believe it is severely eroded shield volcano
Age: This volcano is believed to be 4.2 million years old
Last Known Eruption: Between 5 million and 3.4 million years ago
Towering over the Wrangell Mountains in Alaska, Mount Blackburn holds court as the undisputed king. Due to its extreme height and ice cover, detailed study of its internal structure hasn’t been done but it is presumed to be a large shield volcano with a structure that has been severely modified by erosion. Imagine a giant, flattened dome, its slopes worn down by the relentless march of glaciers. This is the basic structure of Mount Blackburn.
Blackburn's origins stretch back millions of years, with estimates placing its initial volcanic activity around 4.2 million years ago. Geologists believe it was once a much larger volcano, but time and glacial forces have heavily eroded its peak. The evidence of this erosion lies in the permanent ice shroud that blankets its upper slopes, hiding much of its internal structure from view.
Mount Blackburn possesses a complex volcanic history. Evidence suggests periods of caldera collapse, a massive depression formed by the inward caving of the summit area, followed by renewed volcanic activity that filled in the depression and built upon the existing structure. This unique history contributes to Blackburn's dramatic topography.
The mountain boasts two distinct summits: the West Peak and the East Peak. For decades, the East Peak was believed to be the true summit, but new surveys revealed the West Peak to be slightly higher. This 16,390-foot giant holds the title of the fifth-highest peak in the United States and the highest in the Wrangell Mountains.
Despite its impressive size and remote location, Mount Blackburn has a colorful history. One of the first ascents in 1912 was led by Dora Keen, a remarkable woman who braved the challenging terrain long before modern climbing equipment existed. Today, Mount Blackburn remains a magnet for experienced climbers seeking a challenging ascent through a landscape sculpted by fire and ice.
