On Supremacy Rock, facing the road, a small formation called The Pyramid exists. If approached from the picnic area, The Pyramid is the section of rock closest to you. Climb the left-hand arete that you can see from the lot. This arete is just to the left of the West Face route and just to the right of Simple Simon Slab.
This route is frequently difficult to climb due to the groups that occupy Simple Simon Slab. Like it's neighbors, this route is nice, but too short to be of any real interest to most climbers.
There is no pro. A trad lead is the same as a solo. This is, however an easy route to solo or TR, although a fall could likely result in real injury
