Pinnacle Peak

Pinnacle Peak is a mountain summit in the Tatoosh Range within Mount Rainier National Park, accessible via a trail that climbs gradually through forest and alpine terrain. The route leads to a saddle offering views of surrounding peaks and the park's volcanic landscape.

A fire lookout station once operated at the summit from 1928 until 1971, with concrete foundations still remaining from the structure. This facility was part of a broader fire detection network that served the park's protection needs.

The Cal Magnusson Trail bears the name of a notable Cascade mountaineer who dedicated 25 years working alongside climbing expert Jim Whittaker at REI.

The trailhead can be accessed from Stevens Canyon Road near Reflection Lakes, where parking is available for visitors. Hikers should be prepared for terrain that varies by season and wear sturdy footwear suitable for the mountain environment.

This peak rises from an extinct volcanic cinder cone that was partially buried by an ancient mudflow from Mount Rainier. The geological forces that shaped this landscape thousands of years ago remain visible in the terrain today.
