This is the route immediately to the right of Diving for Rocks and is easily distinguished by wide-ish (fist), flaring crack. This crack is the crux of this route - always greasy, it's tough to get your mitts to stick in this thing.
The top rope above this route is 12a, Lonesome Dove.
To the right of Diving for Rocks.
3 bolts + anchors

I don't know what the route out the roof is from the anchor, but Lonesome Dove is at the top of Diving for Rocks, at least according to Sean O'Grady's guidebook. Also, the anchors at the end of the roof are unlikely to be intended for toproping.
Don't know how you could say the crack wasn't incredibly slimy. There is a pretty solid hand jam near the top of the crack. Not using this would make the route way harder or you would have to go off route probably.
