#1: The sign at the roadside park (visit #3)

(visited by Michael G. Koerner, Roger Rowlett and Jeff Woolsey)

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).

These photos are also on my 45N webpage.

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.
