Exactly where the description said it would be. Met the volunteers while I was taking a picture and they had never seen or noticed the benchmark!!!

Found this benchmark [b]exactly[/b] as described in its 01/0/1935 documented history. The problem arises from lack of understanding of the following:

sill
/sil/
Noun
1. A shelf or slab of stone, wood, or metal at the [b][i]foot[/b][/i] of a window or doorway.

I added the bold and italics.

The benchmark lies exactly as described; AT THE EAST ENTRANCE, IN THE TOP OF THE STONE DOOR SILL, AND 2.9 FEET SOUTH OF THE CENTER OF THE DOOR. A STANDARD DISK, STAMPED N 201 1935.

photoAwesome Find

Went out looking for this one with my daughter. Found it pretty easily, although the coordinates from the site here had us on the other side of the building. The description said above the east door so we went there and found it, but below and to the left of the door as was stated earlier in this log by another user. We also found another marker numbered N201A which is roughly NE at the end of the parking lot, near the fountain at the corner of the intersection. Photos of both included.

We were checking out the building and my Dad say "hey,
Check this out!" I laughed out lound and noted the location of the benchmark

Found just as described in good condition.

I found this one on the correct side of the building but in a different location than the description. It is placed on the ground and to the left of the door and not above it. The courthouse was remodled a few years ago and the disk could have been moved then. Onward....
