Regal Mountain is an eroded stratovolcano or shield volcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell-Saint Elias National Park about east of Mount Blackburn, the second highest volcano in the United States, and southeast of the massive Nabesna Glacier. Regal Mountain is the third highest thirteener (a peak between 13,000 and 13,999 feet in elevation) in Alaska, ranking just behind its neighbor, Atna Peaks.¹ Because the mountain is almost entirely covered in glaciers, no geological studies have been done, but published references state and the geological map shows that the mountain is an old eroded volcanic edifice.
Several major glaciers flow from the steep and heavily eroded flanks of Regal Mountain. The Rohn Glacier and Regal Glacier head east and southeast to join the Nizina Glacier, while the Root Glacier flows south to join the Kennicott Glacier just above the town of McCarthy. Each of those large glaciers exceeds in width, but largest of all on Regal Mountain is a massive unnamed glacier, over across, which flows northwest just over to join the mighty Nabesna.
