Sign at the County Fair

For a couple of decades now I have gone to the Washington County Fair and never noticed this sign. Sometimes going to a place off-season and taking a look at it through a different lens yields some interesting finds. 

Mysterious Sign

Over the past 25 years, I have walked by this sign countless times when I walked the dogs. I finally called Washington County to see what it means. It is a sign to mark a section corner on a map of Washington County and stands for "Washington County Reference Monument."

This marker is at the corner of 32N 20W 11 (which we live in), 32N 20W 10 (the section to the west of us), 32N 20W 3 (the section kitty-corner to us and to the northwest), and 32N 20W 2 (the section to our north).  

Originally, when the land was surveyed in 1847, a cedar post was used. Then, in the 1880s, the surveyors used a block of sandstone with an "X" on it. Now, there's a metal sign.
