Center jam cracks up through the upstream-facing face. The hand jams are amazing, though there are a few face holds to help you out.
Just shy of 500 Feet downstream of Juliet's Balcony. There's a large, upstream-facing corner with fist-width cracks throughout. The classic Romeo's Ladder route runs directly up the center of the crack system.
Toprope is best. Can be led with fist-sized pro, but leading at Great Falls is not recommended. Pro pulls out of the rock.
