Mount St. John is the highest point on the divide between Cascade Canyon and Paintbrush Canyon in the Teton Range. The mountain is visible as a serrated ridge on the north side of Cascade Canyon opposite the high central peaks of the range. The summit of the mountain is the highest of many granite towers that are nearly the same height along the ridgecrest.
Orestes St. John
Mount St. John is named after Orestes St. John, who was one of the major geologists with the Hayden Survey that ended in 1883.
more history...

Mount St. John is a mountain in a very central location to public access, yet the higher portions of the mountain are rarely visited in comparison to the canyons and lakes that surround it. The major reason for its solitude is the due to the fact that the main trail into Hanging Canyon on its south side is both unmarked and is not maintained. While Paintbrush Canyon, Cascade Canyon, and Jenny Lake are heavily used areas, Mount St. John stands accessible but silent. Many attractive granite towers surround Lake of the Crags, including Symmetry Spire, Rock of Ages, and the Jaw.

Getting There

To access Hanging Canyon and Lake of the Crags, take any of the unmarked trails that head to the west from the Jenny Lake Trail between Cascade Canyon and String Lake.
