A jagged peak with a huge glacier on the north side. From Golden Hinde it is visible over the top of Mount Myra.
Name Notes: Likely named after a person, Septimus Evans, a surgeon on the S.S. Beaver, and not because of anything like seven distinguishable summits.
The high point of this massif is actually called Mt Rosseau, and the westernmost summit is Mt Septimus. There cannot be a notch/col of more than a few tens of meters between them.
