This may be the most attempted confluence ever! The State of Wisconsin has
placed a small roadside park 300 meters west of the confluence, with a sign and
elevation marker (to the nearest minute). Three reports follow from people
who have visited the park.

07-Nov-1998 -- Visit the most dramatic confluence
in North America. 45 North X 90 West. There's a bar, a club, a song,
T-Shirts and of course a web site!
You're halfway to the North Pole and half way around the Western Hemisphere.

March 1999 -- I was driving around central Wisconsin
on a day off in March of 1999 and at the spur of the moment decided
to pull off of WI 29 to check out the 45N/90W marker (there is a sign for
it on WI 29). I am remiss in not recording the exact date, but it was in
mid-late March of 1999. The marker (picture #4) is in a little park (shown in picture
#2) just off Meridian Rd (it is the elevation marker shown on the USGS
map of the area on the TopoZone map). The marker is in front of a
sign shown in picture #1. The actual 45N/90W point is in the
private farm field in the background, about 350 meters behind the
sign (Marathon County was apparently unable to secure a park at the site iself).

Summer 1999 -- Since I took [these pictures] (last summer)
before discovering your site (this evening), the surroundings were not
photographed. I had DGPS available, but it stayed in the car. The spot
that the DGPS liked better was about a quarter of a mile away, in a
ditch by the side of the road that intersects the one this park is on.
Room here for maybe a dozen cars to park on the grass inside the
chain-link fence; nevertheless I was alone here that afternoon.
Note that the resolution on the monument is nearest minute of arc, which
is about a mile in any direction. This uncertainty is much larger than
that from forgetting which datum I was using, though given the probable
age of the monument I think I used NAD27 CONUS. That there's a monument
(no control number, so its accuracy is suspect) here at all is probably
more interesting than the swampy spot 1/4 mile away. The nearest NGS
monument is more than five miles away.
