Wax On Wax Off

This problem sits on a squat slopey boulder behind the Fortress of Solitude Roof. It is separate from the boulders that make up the 'Fortress'  Start sitting on the left side of the block in a good notch. Traverse the lip until you can throw a heel and rock over. Harder than it looks.

Go through the Fortress and out the back. Follow the back entrance 'walkway' and this will boulder will be just on the left and slightly downhill.
