Precipitation runoff from the mountain drains into Three Saints Bay and topographic relief is significant as the summit rises 3,337 feet (1,017 meters) above the bay in approximately 1.5 miles (2.4 km).

[3] The two peaks were described and named in 1931 by the United States Geological Survey but the toponyms have not been officially adopted by the United States Board on Geographic Names.

[2] The peaks are named in association with Three Saints Bay, which was named by Grigory Shelikhov who established the first permanent Russian settlement in North America along the shore below the west peak in 1784.

[5][6] According to the Köppen climate classification system, West Saint Peak is located in a subpolar oceanic climate zone with cold, snowy winters, and cool summers.

[7] Weather systems coming off the North Pacific are forced upwards by the mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall.
