A number of tephra layers between 18,100 and 55,400 years old, found in Siple Dome ice cores, resemble these of Mount Berlin, as do tephras emplaced 9,346 and 2,067 BCE (interval 3.0 years) in the Siple Dome A ice core. The marine Tephra B and Tephra C layers may also come from Mount Berlin but statistical methods have not supported such a relationship. A 694±7 before present tephra layer found in the TALDICE ice core in East Antarctica may come from Mount Berlin or from Mount Melbourne and may have been erupted at the same time as an eruption of The Pleiades.
