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. | |||
