There was an article about it in the 1960s, probably “Argosy” or “True” magazine (my dad subscribed), and as a consequence, during a family vacation, I climbed the thing. It was already being studied, but like most Precolumbian sites, it consisted of, well, a freakin’ mound of dirt. I would have preferred to have taken a station wagon trip to, say, Egypt or Greece, but they hadn’t put in the freeway yet. ;’)
Yep. Usually they contain bones and surprisingly few artifacts, so unless they are unusually large, they are forgotten or of only local interest.
