yesterday's example, it's clearly associated with a vertical fracture, almost certainly a fault. The reason I don't simply assert that it is a fault is that I would need to demonstrate some evidence of offset parallel to the fracture, such as displaced layers, broken clasts, slickensides, or something along those lines. Obviously, I couldn't get close enough to do that, so I have to leave open the possibility (however slight, in my opinion) that this is simply a set of parallel joints.
