Tahtlum Peak

You must be logged in to add a peak to your favorites.

Tahtlum Peak is located about a mile east of Mount Rainier National Park in the William O. Douglas Wilderness. It's situated immediately north of Dewey Lake, with Dewey Peak immediately on the opposite side of the lake. Water drains off Tahtlum Peak into American River, which eventually makes its way into the mighty Columbia River. Therefore it stands to reason Tahtlum Peak is on the east side of the spine of the Cascade crest, which it is ever so slightly.

Tahtlum Peak is connected to Naches Peak (to the west) by a high ridge. Approach can be made from Chinook Pass along the Pacific Crest Trail, then follow the connecting ridge to the summit on an established climber's path. If you aren't on the path, you are making it more difficult than it needs to be. It's a dayhike and class 2 scrambling. Allow 4-5 hours round trip.

From the small summit (a level flat 40 square foot space) a nice panoramic view unfolds in all directions. To the west Mount Rainier dominates everything, along with all the peaks on the east side of the park from the Tatoosh Range to the Sourdough Range. To the south, Mount Adams and the Goat Rocks. To the north Crystal Mountain and Chinook Peak. The Stuart Range and Mount Aix can also be seen on clear days.

"Tahtlum" is Chinook jargon, translated it means "ten". Tahtlum Peak can be seen from Highway 410 on the east side of Chinook Pass. However, the road over Chinook Pass is closed during winter due to snowpack, check road condition status before attempting.

    Started from Chinook Pass about 10:30 AM, following the Pacific Crest Trail to the highest spot east of Naches Peak. Just a little farther south along the PCT, paths branch out in all direction....
