Somebody probably has a better name for this area, but the headwalls above the slabs of the northeast side of yonah offer some of the best concentration of good problems on yonah. This small area has a number of problems with lots of variety. some of the problems can seep in times of defrost or periods of heavy rain. It's a hefty hike with 1100 feet elevation gain to get to these boulders. There is some more potential bouldering further down along the cliffline of the headwall. There's another nice headwall feature with good potential for bouldering about 200 yards northeast of the army camp downhill. There's a little more stuff further downhill.
From the army camp near the top of the mountain, take the small trail that goes sharply uphill towards the top of the mountain. When you intersect with a dirt road, go uphill and left on this road. In about 100 yards, the dirt road will curve to the right. look for a old rotten log on your left at this point and walk along it and along a faint trail to the boulders about 200 feet away
