Yeah, kind of. It was rough, solid, and pitted, just like it looks. It was intact, for the most part, with little-to-no flaking, crumbling, and/or soft spots.
Well, if nothing else, I feel better that y’all are baffled as much as I am. I really cannot offer any more info and/or insight, except for the fact that this was a homeowner-built-house, erected in the sticks, with no enforcements/regulations whatsoever. And judging by the looks of some other conditions at the property, I can quite honestly say that the construction practices observed were, to say the least, less-than-professional.
