Regal Mountain
Encyclopedia
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 19 mi (31 km) 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
. 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 15 miles (24 km) to join the Kennicott Glacier
just above the town of McCarthy
. Each of those large glaciers exceeds 1 miles (1.6 km) in width, but largest of all on Regal Mountain is a massive unnamed glacier, over 3 miles (5 km) across, which flows northwest just over 10 mi (16 km) to join the mighty Nabesna.
Stratovolcano
A stratovolcano, also known as a composite volcano, is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions...

Shield volcano
A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. They are named for their large size and low profile, resembling a warrior's shield. This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from more explosive volcanoes...
