Wolf Creek again....!
OK, last time, I found what appeared to be Egyptian ruins. Now, on #1, I saw these small columns. After comparing with my extensive collection of ancient artifacts, these appear to be Roman. They slightly resemble some Greek architecture but my money is on Roman.
I, for one, believe this supports the idea that aliens were among us, as far back as ancient times. The aliens inspired many cultures, some of which are on display, right here on Wolf Creek.
