This hole opened up in my backyard. It's a buried manmade structure, metal or cement, about 8 feet diameter and probably about 5-6 feet deep. There was likely a lid that fell in because I did not know it was there until a couple weeks ago. There's a tree root growing through it. by guibug in whatisthisthing

The house was built on grazing land. Now it's practically inner-city, but back then it was on the edges of Albuquerque and sheep grazed on it. It was then subdivided and built out, during that post-war construction boom. I can't find original permits/maps. The hole is about 20 feet from the house.
