Mt. Gilbert is a pyramid-shaped peak, possibly qualifying as a glacial horn, AKA pyramidal peak (British usage?). As you can see below, it's bounded on the west by the large bowl-shaped head of the glacially carved, U-shaped Seitz Canyon; it's bounded on the northeast by a high, well-defined cirque; and it's bounded on the southeast by an irregularly bowl-shaped area, also a cirque.

|Same map, with the outlines of three circular depressions or bowls formed by glaciers. As you can see, the west side of Mt. Gilbert is essentially one arête. Other horns and arêtes are present in the topo image.|
|What do you think? Is it a horn?|

possibly with sill-like intrusions of granite.
