Geo 365: Dec. 13, Day 347: South of the Stack

...looking north. This is the same sedimentary breccia as the last couple of days, but I think there's something else going on here, as well: a significant shear zone dipping to the right. In addition, there's much more secondary mineralization on this face, as compared to the east face, which can be seen as stringers and vein-like features all over the exposure. As we'll see tomorrow, this material is weathering in relief- that is, it's more resistant than the rock around it- and I think it's probably quartz.
