Old Tom Mountain

Elevation: 8,733 ft

This peak is found on page 356.


Please be advised that there is a major typo in the book. I wrote that the route climbed the west ridge when I should have said the “south ridge.” Darn! Thanks to Martin Neunzert for emailing me and pointing this out. Martin wrote:

I made an attempt on Old Tom Mountain yesterday, from Garden Creek Gap. But when I checked your description in the second edition of Idaho: A Climbing Guide (page 356), it says “…west ridge from Garden Creek Gap.” Clearly, this is the south ridge.

In betterment,

Old Tom is most often climbed via its south ridge, but has also been reported to have been climbed from the Goodenough Creek Campground area on its northeastern side. This description is for the south ridge route from a 2008 climb, contributed by Margo Mandella.

Travelling south on I-15 from Pocatello, take exit 40, Arimo Road, and travel west to Garden Creek Gap. The gap area itself is a technical rock climbing area. Park in one of the two dirt pull outs past the big rock walls.

Hike toward the south end of the mountain and walk along the dirt track that travels northwest, looking to your east for a lessor ridge to use to reach the mountain’s main south ridge (there are several options).

Travel along the south ridge until you reach a prominence that you will have convinced yourself is the summit. It is not; just a very convincing false summit. Continue north to the true summit. This route is approximately 8 miles round trip, has no water, and few trees once you are on the ridge.
