Double Sets of Section Corners...

Need to move this to Survey-Related Category

It does sound confusing doesn't it.

I've often wondered why they couldn't be bothered to set the closing quarter corners.

For that matter, why was the center corner left out of the vast majority of original surveys?

Setting the center 1/4 corner would have more than doubled the survey mileage per township, assuming the regular procedure of intersecting the 1/4 lines was followed.

I won't go into the GLO's logistics and rationalization of costs for the procedure suffice to say that is the decision that they made. Remember that the deputy surveyor subdividing the township was charged with running up and closing into the exterior. Retracing all the miles on the exterior to set the intervening quarter corners would very likely have run into a lot more expense on lines that already existed and invite problems when the retracement differed from the previous record. It was to be handled by office procedures.

The position for the North quarter corner was defined by the protractions shown on the plats created after the fact by the GLO and memorialized by the little colored or dashed lines shown on the plat. The acreages of the lots, particularly along the boundary are sometimes necessary and informative in order to determine where GLO intended it to be and upon which the patents from the US are based. Very often not at midpoint in the midwest anyway.

there.

I said it.

Well, they set them in Illinois and Indiana.

So how do they do it in other PLSS states? Show the shift difference from the standard and closing corners, but didn't set monuments for the closing corners?

Or did they just accept the standard corner(s) as the common corner(s)?

Some confustion the thread title implies double section corners but my interpretation of the original post was refering to the quarter corners on the boundary of the closing township. Standard quarter corners (or corners on the senior township) were of course set along with all section corners.

Hey Holy Cow,

The "holy cow" theme is funny....I can understand why they did not set the centers given the costs. When you read the special instructions they seem to be very wary about the costs...as they should've been. If you were paying for it? Thanks for getting back to me.

Hello Jim,

I agree, time is money.
Thanks for getting back to me.

Hello jlwahl,

Thank you again for your input.I'll look into the shading and have been reviewing the area calculations in the lots. I appreciate your insight.

Thanks,

The Standards were run to begin another layer of townships that are regular and then every four townships, a Standard is run again.

The townships to the south of these Standards only were required to set a closing corner by tying one way to a Standard corner and retracing the Standard was not deemed necessary. Hence the 1/4 corner for the sections below the Standard were not established.

Probably a mistake to do it that way since the 1/4 cor. monuments on the Standard were sometimes confused as being common corners to the south.

But that is how it was.

Thanks Keith,

Ok...that clears things up. So closing to a township line with existing monuments you run random northerly parallel to the east boundary towards the objective corner...reaching the line closed upon you search for the existing monument...once found you adjust and run true back correcting to a permanent monument.

Closing to a standard parallel you run northerly parallel to the east boundary, no objective corner on the standard because the corners there control the to the north, you search east and west and record the distance to the adjacent corners.

Got it, Thanks again for your help.

Yes, the key point being that they did not have to retrace the Standard to close on it, only tied one way, therefore the 1/4 cor. to the south was not set.

Ok...Thanks Again Keith
