Approaching the bridge from the south side, descend left just off Beach Dr just before crossing the bridge into a small area by the side of the creek that has a single prominent boulder positioned on the waterline - Wide but thin, looks a bit like a giant sharks fin.
The bank-facing side of this boulder has a couple lines on it, and the rocky side-wall to its left has a few easy, slabby problems.

Oddly enough, there's a photo of Theodore Roosevelt climbing in this area, on the slabby area down the bank a little bit.

Notice the massive flake off to the right?

From Blagden Ave NW take Beach Dr north until you reach the boulder bridge (half a mile or less). From Military Road, take Beach Dr south until you reach boulder bridge (more like a mile).
