|Castle Rock - South Face
This route follows the curving crack to the left of Pollo Negro. Once the crack ends, you do a bit of face climbing and clip one bolt to access the right leaning crack above.
There are no fixed anchors, so the route ends once you get to the height of the chain anchors of Pollo Negro over to the right...lower off those.
However, there is a nice and easy crack that continues up for another 40+ meters.
South face of Lone Rock (AKA Castle Rock), to the left of Pollo Negro.
Trad gear and 1-3 bolts.
