Zoom in a bit to the left of the pink pin flag. There’s a 4×4 CM with a N&D there. The disc does not bear the licensed business number of the platting surveyor. I found a 1/4” rebar where I’m digging. I poked all around it with my machete, but couldn’t find any concrete. I don’t know why someone would’ve set a 1/4“ rebar that’s typically used for a CM without the concrete unless they ran out of concrete. I’m not sure if precast CMs were around in 1970, which is when this plat was recorded.

I have had my 2nd C-1/4 pincushion discovery this last month in my 35 years of surveying. The 1st one was about 15 years ago and they were about 12′ apart set by the same surveyor. This last one was 0.7′ apart and set by the same surveyor. But each 1/4 corners were different surveyors. They pincushion themselves.

Fully expected to find two pincushions early this week. Found nothing in both cases. That is pathetic. The reason? A nationally known land surveying firm was in this area a couple of years back working with a major industrial wind turbine installation spread over a very large area. Many PLSS sections involved in numerous townships. We have stumbled onto a few bars with their caps. In a section from six months ago we found a bar/cap at the “X” of quarter section lines for the center corner. This week’s findings were non-existent at both of the “X” locations and at the corner frequently used per physical evidence in each case. BTW, none of the corner reports have ever been filed with the State or the County.

I’m curious to see what a Kansas corner report looks like. Think you can post one for me?

If you are in a “typical” Florida subdivision it’s not at all unusual to see that. After PCP centerline monumentation became mandatory, and even before, most lot corners were derived from centerline and lot or block corner evidence instead of the plat boundary monuments. Most Surveyors will search for C/L control or front corners first. If found or set they will often be used for locating or setting the rear corners. Thus the pincushion.

Sounds a lot like up here in the western Washington.
”Held centerline of 5th Ave NE monuments for Basis of Bearing”.
”Found rebar with cap (insert name of original Plattor) N 0.29’ & E 0.31’, set prop at calc position”

Here is one picked at random. Not mine, BTW.
There a 2 purposes for reference marks. One is as an aid to find the monument. The other is as an aid to accurately restore an lost obliterated monument from the references. When a person uses a fence post and the centerline of road as a reference I’ve got to think that he is assuming the former. But when he offers offsets to the hundredth of a foot I’m thinking the latter.
For the record I’m in the aid to restoration camp.

No latitude and longitude, but SPCs. I like the source description, since I’m always looking to see how a position was derived.

Would be interested in seeing examples from other PLSS States.
In recording states, the filed survey is what the surveyor should be looking at to determine what to follow and how. The corner records are primarily there to alert future surveyors that somethng did exist and how to find it based on nearby objects. Fence posts, power poles, telephone boxes and culvert ends are the most likely items to be chosen in rural areas, with nails driven in or “X” marks etched. In urban areas, curb returns, concrete corners, house corners, water or gas valve lids, etc. get added into the mix. May not work 100 years later, but, then, neither will coordinates.

Not sure where you’re located but I was surveying in southeast Iowa in 1970 and I definitely recall schlepping my share of 4” x 4” x 48” precast concrete monuments over hill and dale at that time.
