Any ideas?
That is a surveyor’s mark called an Above Ground Marker. It is used as a point of reference when they survey they land.
Its called a benchmark, used by surveyors as a known point from which to take readings. We had a benchmark on the edge of of our property in the town where In grew up. It was a square, white marble column, like a truncated obelisk with the point cut off to make a 4" square flat top, buried at the roadside and standing a couple inches proud of the grass. It had a cross with a dot in the middle, and a geodetic ID number engraved on the top.
Nailed it with the lawnmower once or twice. That’d really put the Fear in you.
My grandma has a little concrete thing like that that marks where her property ends (or where 1 part of it ends, legally it’s 2 rectangles sharing a side). Once after not mowing for like a month and a half I forgot it was there and totally ruined the freshly replaced blades 🥲
Control point for ley lines. Keeps the magic channeled to prevent chaos from breaking out.
I left reddit partially because every fuckdamn top comment in an info request thread was a joke.
You guys seriously going to make that the norm here too?

Well we like to have a little fun around here, keep it loosey goosey ya know, a little bit of sillyness goes a long way.
A marker point for geodetic marking. Also known as triangulation station or trigonometrical point, it’s fixed to the ground with its known coordinates.
Cool! Interesting, I thought True North meant that they somehow pointed north given another reference. Thanks for the info.
They hold the sidewalk down, don’t pick it up or the whole block could blow away.
![[Solved] Anyone know what this is? They are embedded in the sidewalks around the city(programming.dev)](https://programming.dev/pictrs/image/17e2a431-e194-46bc-8e69-34c6419ac8da.jpeg){kind=link}
