In Florida we used symbols that looked like arrowheads to represent section and 1/4 corners. Section corners had 4 arrowheads pointing at each other; 1/4 corners had 2 arrowheads pointing at each other. Does any Florida surveyor remember using these symbols? I spoke with an old registered surveyor at work this morning. He heard the arrowhead symbols originated from a Florida sugar company who used the symbols on their maps.
I don't know where it originated but variations on the theme are ubiquitous.
The section corner symbol with sections 21, 22, 27, and 28 is exactly correct. Do you have a quarter corner symbol?
@field-dog Yeah.
I don't use the arrows actually, I just extend the section linework through the corner a little bit to make a plus sign and then stick the section numbers in the corners of the plus. At 1/4 corners I just put the section numbers on each side of the line, kitty corner from each other, near the monument symbol.
With the section numbers above and below where the arrowheads meet, right?
You do you. There is really no fixed standard to this.
That arrow symbol used to be standard on the little green timely template everyone used to carry in there field book or shirt pocket. Various Open or shading on the symbols indicate set or found.
Is there any requirement to show a section corner differently from any other survey corner. I don't recall ever seeing such a dictate.

I've not seen that the arrows are the standard for section labels, but I'm familiar seeing them.
And Rankin is right that they often appear in hand drafting devices for field books/office drawings. The only one of those devices I have left is a long one about 6" and it has a ruler, bunch of circles of various sizes, the arrows, and curves on each end, it's labeled a "COMBO COMPASS RULER" you may have seen them back in the day. I don't use it anymore except for the ruler part to check scales on drawings.
We normally symbol section corners like any other corner, what type of monument is there and have that symbol appear in the legend. If you're to use those arrows then the monument needs some type of description, if each one is labeled with text, it would take up a lot of drawing space.
My preference is to use the same symbols as I would use for other monumented corners. The difference is that they will have a label saying: Northwest Corner of Southwest Quarter of Section 14-18S-21E, Found 1/2" iron bar with unreadable yellow plastic cap, origin unknown
I have seen many other surveyors using a symbol that consists of a triangle with a center point positioned at the intersection of the boundary lines. Some use them only on the exterior Government-set corners while others use them as well at any aliquot corner.
I looked into this a few years ago, and posted about it here:

Fits snuggly in my work shirt left front pocket. Too bad they never made them orange-colored.
