==Volcanic history== | |||
Older volcanics are exposed at Brandenberger Bluff with dates ranging form around 2,738,000 ± 63,000 years ago. Brandenberger Bluff lies northwest of the main summit and unlike the rest of Mount Berlin, which is formed by flow rocks, Brandenberger Bluff is formed by layered hyaloclastite tuffs. Phonolithic and phonotephritic rocks are found at Brandenberger Bluff. Over time, the contents of iron in the rocks erupted by Mount Berlin increased and that of silica and potassium. | |||
