DESCRIPTION
From Miller and Richter (1994) [1]: "Both Mt. Bona and Mt. Churchill are high snow- and ice-covered mountains in the eastern part of the Wrangell volcanic field. They appear to be relatively young constructional forms. Mt. Bona, the highest peak (5,005) in the Wrangell Mountains, may be a small stratocone built upon a high platform of Pennsylvanian and Lower Permian rocks [2]." McGimsey and others (1992) [3] state that Mount Churchill is now known to be the source of the White River Ash, produced during two of the largest explosive eruptions in North America during the past 2000 years.
