Directions: Leave Montana Highway #1 approximately 12 miles west of Anaconda, Montana turning south on the Storm Lake Road #675. The Storm Lake Road is good for approximately six miles. Then the road begins to deteriorate over the next ½ mile. Depending on your vehicle it’s a good time to find a parking place. For those brave drivers in a high clearance vehicle one can navigate large gullies, potholes and boulders to reach Storm Lake. From Storm Lake, travel 2.3 miles on trail FS#41to Storm Lake Pass. At the pass, locate a very intermittent and faint ridge trail to the summit.
