Weird field in Bingham?

Dear fellow Strange Mainers, please find following an inquiry from another of your number regarding a remembered weird Maine spot:

Quick question, I grew up in Maine (Bingham) and my buddies in high school used to get a big kick out of this spot off 201 between Skowhegan and Fairfield. I want to say is was on the Hinckley road in Clinton (rte 23) but can’t really remember.

Anyway, it was this weird field with crazy mounds and hills shaped like humans dug into the earth. And rock circles and all kinds of stuff. My buddy said there was a orphanage across the street in a big abandoned farm house, but it wasn’t really an orphanage because it was run by a cult and they used to human sacrifice the babies. I’m sure he was full of sh*t but the field was really crazy. I still remember it, I wish I had pictures.
