'''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 {{Convert|19|mi|km|0|abbr=on}} 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]].<ref name="peakbagger" /> 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 {{Convert|15|mi|km|0}} to join the [[Kennicott Glacier]] just above the town of [[McCarthy, Alaska|McCarthy]]. Each of those large glaciers exceeds {{Convert|1|mi|km|1}} in width, but largest of all on Regal Mountain is a massive unnamed glacier, over {{Convert|3|mi|km|0}} across, which flows northwest just over {{Convert|10|mi|km|0|abbr=on}} to join the mighty Nabesna. __TOC__{{clear}}
