The peak is not named “Bad Rock” for nothing. Every approach crosses loose talus which will make some cry. Despite the fact that it is stuck between two Idaho 12ers, Leatherman Peak and Mount Church, this is one of Idaho’s great peaks.

Bad Rock Peak from somewhere in Lone Cedar Creek. Lone Cedar Creek is tough to traverse in its lower reaches and after you accomplish the task you are treated to acres of talus. Its true wilderness up there.
1) Lone Cedar Creek. [(B)(9)]
Not many people approach the peak from this drainage because it is trailless. Like many Lost River Range drainages the bottom of Lone Cedar Creek in its lower stretches is difficult to traverse, especially during high water. Nevertheless, this approach is rewarding for those who like wild country.

Once you get through the difficult lower sections of the drainage you are confronted with acres of talus to negotiate.
The talus varies in size from almost sand-like scree to large, tipsy rocks.
The saddle between Bad Rock Peak and Mount Church can be reached by climbing this debris filled gully.
From the low point on the saddle you can good progress to the cliffs below the summit. These cliffs involve Class 5 climbing. However, you can find a goat path across the face to reach the peak’s north ridge.
2) Sawmill Gulch and Pass.
Sawmill Gulch has everything that Lone Cedar does not have, a road, albeit a rough road, to a high elevation and then an actual trail that leads first to Sawmill Pass and then on to Leatherman Pass. Nevertheless, if you are going to Bad Rock Peak, you still are going to have to deal with a lot of talus as you drop down off of Sawmill Pass into the upper reaches of Lone Cedar Creek and then climb up a steep talus slope to the peak’s north ridge.
I have not traversed Sawmill Gulch since 1993 but recent reports state the road and the trail are still in passable condition. As far as scenery goes, the trail crosses some great country.
You can find flat places to camp near the top of the pass. The view is to the west and the Pioneer Mountains.

Once you get on top of Bad Rock Peak’s north ridge you will see a clear line to the chimney on the summit block.
