Adam, The thin finger crack that starts off the left side of the ledge is the upper half of the 5.8 crack you're talking about. It has good gear and is 5.10. Well worth leading.

Great route - no cheating....stay away from the crack both low and high as there are face holds that go directly up the bolt line. Crux section between bolts 2 & 3.
Thin brass nuts work good in the upper left crack...the gear gets a little patchy for a bit but its good enough. The crack ends at the same anchors for welcome to milagrosa.
