thats a four foot rod, i jabbed it in the ground and it sank about a foot when i pushed down on it it just kept going. the ground was solid on top i even drove across the area later that day.
So your the one who popped the real estate bubble.;-)
Obviously there is some kind of void there, did you try other places, and did the ground do the same thing?
when i think of the term 'sink hole' i think of a hole or depression in the ground. that looks to be level with the ground. quick sand is the first thing that popped to my mind, but i am at the foothill of the appalachian mountain and have zero experience with and find of sand. we have 2 types of soil here - clay or rock.

Now, see, I wouldn't have done that.

If you were looking for an old wood post corner, you may have found it! That's pretty much how a 100+ year-old Mineral Survey Corner Post “feels” when you are probing around in Nevada. Excavate a little, and see if there is rotted wood, “bug dust,” or other anomalous organic remains.

Sink holes swallow cars!!
That looks to be an old bear trap, maybe lion pit? LOL
Around these parts most of our sinkholes are the result of filled over stump dumps..

I knew you were a smart man Don.

I think its a stump hole. We found all the corners which were very old pine posts which are typical around here. When pulled it out water filled the hole so maybe a spring.
When I was a kid living in Mississippi I found ant beds you could sink a pipe in to that deep. Of course I had flooded it with the water hose first.
I've never seen one, but here in Scotland the entire country was glaciated in the last ice age and 'kettle holes' regularly turn up, they are voids in the glacial clay where there were solid lumps of ice. They can be metres deep and tens of metres long.
I have something similar about 10 feet into my yard directly from the front door.
It gets filled a few times a year and apparently has no bottom as I have stacked half a dozen pieces of fire wood end to end inside and they will disappear also.
What type of stable monument are you gonna set there?

You drove over the prism?:-O:'( and it survived?:-O You have really good equioment!;-)
Now is the time for all good men to come to the aid of their country. Typing class 9th grade!
Hey, my particular expertise is finding places to sink the truck down to the rails 😉
Two possibilities. First, could this have been the former location of a power pole? Second, and far more dangerous, any possibility this could be the location of a very old well? We were doing soil compaction verification on a motel site that required as much as 30 feet of fill. Not too far into the process, all heck broke loose near one corner of the project. A water well was discovered with a depth of over 90 feet. Hand dug well, not drilled. It was about four feet in diameter. Only the top few feet had been blocked off by someone many years earlier. The area had been the site of about 15 little shanties that had been the homes of families with some roots in Africa in a community where they were not treated well. ( see the movie: The Learning Tree by Gordon Parks)
The well was located almost precisely where one of the building piers was to be placed.
Thats fun knee right ther. 2 types of soil clay and rock...
I didn't know there were prairie dogs in Mississippi.
"quick sand is the first thing that popped to my mind"
Working with my brother last week measuring stockpile volumes for a gravel mining company. Running two rovers, I asked him on the first pile you want top or toe, to which he replied toe. Second pile was an 11,000 Yd+ pile of concrete sand which fell on the edge of a previously mined pit now brim full of irrigation water. As I finished my top shots I met him on the backside of the pile with mud and sand up to his waistband. We both had a good laugh.

THATS NOT A SINK HOLE
This is a sink hole

The ground around felt solid as we stood on it. I think it was an underground spring that had saturated a layer of sand which would cause this type of thing. Just never seen it covered with a solid layer of topsoil before.

I was thinking more of a unique void or "fissure" that you just happened to find before you said you thought it was an old stump hole. I've found a few (3 or 4) of those around here, maybe 2 feet deep. They are curious for sure, but not unheard of.
