This is the wide slot on the West face of Fin City. While appealing to climb, leading this is an entirely different proposition, since the bulk of it may be only protectable with Big Bros or 2 x 4s. The climb has a benign appearance, but looks can deceive as the left wall, which you use for you feet, has somewhat of a friable feel to it, still, due to lack of traffic or rock quality, or both. It is probably best to climb it right side in.
This is on the West face of Fin City. It is the obvious slot/chimney.
Big Bros, an Alien and #5 Camalot may help.... Apparently, 2 #5 Camalots can be helpful.
