I found this disk at Acton Lake in Hueston Woods State Park, Oxford, OH, 45056.

I searched NGS database and geocaching.com database, still no info on it.

 

Does anyone have official info on this? Coords are: N 39* 55.7032,W 084* 73.8135

 

Picture provided on request.

Help us a little, what is on the disk, both cast into and stamped.

 

What agency? If U.S. GEOLOGICAL SURVEY then 90% of those marks are not in the database.

Hi--

 

"Coords are: N 39* 55.7032,W 084* 73.8135."

 

These don't work on our finding aids, because the longitude has a minutes value that exceeds 60. Some sort of typo, we imagine.

 

We'll check back in case of a correction.

 

Best,

m&h

Coordinates can be expressed by three common methods. I expect the original readings were in decimal minutes, and the other values converted with a pocket calculator, with the first posting incorrectly formatted:

N39.557032 degrees W084.738135 degrees

N39d 33.422' W084d 44.288' as usually used with geocaches

N39d 33 25.32 W084d 44' 17.28" as found on NGS data sheets
