Cathedral Peak has a subsidiary summit to the west called Eichorn Pinnacle, for Jules Eichorn, who first ascended a class 5.4 route to its summit on July 24, 1931, with Glen Dawson.

In 1869, John Muir wrote in My first summer in the Sierra: The body of the Cathedral is nearly square, and the roof slopes are wonderfully regular and symmetrical, the ridge trending northeast and southwest.

The gable on the northeast end is magnificent in size and simplicity, and at its base there is a big snow-bank protected by the shadow of the building.

Here too the joints in the rock are seen to have played an important part in determining their forms and size and general arrangement.

Cathedral Peak is the youngest of the rock formations in the Suite, dating to the Cretaceous Period at 83 million years ago.
