Fault at Tent Rocks, New Mexico

The simplest interpretation is that these are normal faults because the overlying block of rock (the hanging wall to the right) is offset downwards relative to the underlying (the footwall to the left). However, one doesn't know if the rocks on either side also moved toward or away from the viewer, and so it could be a strike-slip fault with a hanging down wall component. Note that as one moves away from the slip surface with the most movement on it, the amount of movement on the slip surfaces appears to diminish. Overall these rocks and the deformation is part of the Rio Grande Rift.
