According to the law of Moses, altars are supposed to have ramps, not stairs.
26 Neither shalt thou go up by steps unto mine altar, that thy nakedness be not discovered thereon. (Exodus 20:26)
The divine name YHV from Mount Ebal, written in proto-alphabetic script.
One reason scholars are skeptical that Nephites ever lived in Mesoamerica is that Mayan culture used steps, not ramps, for their altars. In North America, at least in Book of Mormon times, the ancient people built ramps.
