Interestingly, the LiDAR / 3D data appears to show erosion patterns somewhat similar to those seen along the Sphinx enclosure walls.
Here, though, gravity is the key clue. For water erosion to produce these features, the water needs a plausible downhill flow path, as we see with Roman aqueducts and similar ancient water systems.
