That matches the marker in my GPS:  N 47 44' 49.7"  W 90 19' 58.6"

I usually wasn't getting any better than 20' accuracy with the GPS in the car,
and even out of the car it rarely got the differential signals.

We were right along the boarder of a subgrid.  The trail in my GPS shows that
I entered the parking lot in en47tr then crossed to en47ur (+- 20' :-)
