Porphyry Peak
Porphyry Peak is a high mountain peak at an elevation of 2.500m (8,202ft) above the sea level, located in Cascade County, in the U.S. state of Montana.
The road to the summit, located within the Lewis and Clark National Forest, is gravel and rocky. It’s called Forest Service Road 834. It’s impassable in winters.

At the summit there’s a lookout tower built in 1960, with spectacular views.
