Triangle Face

A quintessential Rubidoux slab, made more exciting if approached as a highball boulder problem and without dodging over to the arete too early. The old Hellweg/Warstler guide (that most everyone disliked) claims there are two distinct 5.10 routes on this boulder. The Fry guide probably gives a better description by stating that "many variations are possible." A good slab to play around on and develop that footwork.

Crashpads or toprope (kinda tricky to set up as I recall)
