As a reviewer I get to see projects with situations I have not encountered in my many years of surveying.  Today's case involves a Section 1 where the north line is a standard parallel relative to the official baseline relevant to your location.  This standard parallel would have been set out in about 1830.  The sections would have come along later and, most likely, would have been the work of different contractors to the Government.

This particular Section 1 was found to measure around 6400 feet north/south.  It is also about 200 feet extra long along the north line.  Those working in PLSSia know that the south half mile of Sections 1-6 were designed to be the standard 40 chains.  The south half of the northwest quarter and the northeast quarter were to be the standard 20 chains.  The north half (sort of) of the NW4 and NE4 would be whatever it happened to measure, but, usually not too far away from 20 chains.  That creates four Government Lots directly below the north line.  In this case, 20 chains grew to be about 37 chains.  That would be an extra 34 acres, more or less, per Lot

It seems like someone lost count of how many half miles they had run north along the township line.

It's wide east-west along the north line? That's unusual for a Section 1. Wide for record or found to be wide?

@mightymoe    This section is very close to 2770 feet from the northwest corner to the north quarter corner. Then 2664 to the northeast corner.  They found monuments at the NW, NE, SE and SW of Section 1. Some prorating took place to set the south quarter corner and east and west quarter corners.  The center section line was run from the south quarter corner and parallel with the east section line per instructions of the time period of the original survey.  The center and north quarter corner were then set.

The southeast corner and south quarter corner of Section 36 to the north (and west) were also found monuments roughly 2650 feet apart.  I have only the final drawing and the comments about the prorating and following original instructions.

The four monuments along the standard parallel happen to be in a straight line even though the original corners were allegedly set on a latitudinal curve.  None of the monuments found were original.  This survey is in a county where I might have done two surveys and nowhere close to this location or the standard parallel.

@holy-cow If I understand your description correctly, it sounds like there would have been enough excess to make Section one standard, with a tier of 4 lots on the north consisting of +/- 34 acres each?  This response is not addressing the issue of non original monuments not being on the latitudinal curve.

There are 2-4 townships south of an area i work in that have 6500-7000 n/s south sections 1 through 6.

@cv 

Yes.  That could have been done.  But, that was not the GLO procedure.

Take a look at page 26 on the link below to see the GLO procedure used in Missouri for such situations.  Theirs is an extreme example but the one used there as they had standard parallels that were very far off from the standard distance.

Use the GLO-BLM portal thread to access the updated PORTAL.  Then scroll in to Missouri.  Go to the Kansas-Missouri border.  Look for Missouri township that is 39 north and 33 West. In a glance you will notice huge sections bumping up against the standard parallel.  I'm not familiar with the naming procedure for all of the atypical aliquots.  Hope someone in Missouri finds this thead and chips in with real world experience.
