[Hide Comment] Edited after going back: I'd climbed a line (on lead, but with basically no pro) that I thought might be this but was probably starting to the left and traversing over. I didn’t start on the blunt arete.

Old notes list a couple of climbs/variations on the cliff.
12/26-30/97 New Routes at the Old New Place, New New Place
First ascent teams including Theo Takeda, Luke Laeser, Carlo Torres, and Scott Fitzgibbon finished 4 new routes at the Old New and New New Places over the Christmas holiday. The first and best, "Momentum" *** 5.12a climbs the smooth, overhung face just right of "God Route" (on the far left side of the crag). On the other end of the cliff, "Half Nelson" ** 5.10d scales a short double overhang. And in the middle of all this, a variation up a smooth grey slab called "Jump Chump" * 5.11+. Oct 7, 2015
