How Geocaching Works
Use of geocaching.com services is subject to the terms and conditions in our disclaimer
A geometric puzzle that uses mathematical skills. No actual
coordinates are given to begin with. Start by finding places from their description, marking their coordinates, and solving for the final cache location using those coordinates.
Note: The coordinates listed above are for the general area
only and have no significance in solving the puzzle.
Several people have found the location but have been unable to reach the cache. If you think you've found the right place but can't reach the cache container, send me an e-mail describing the location and if it's the right place, go ahead and log the find.
The final cache site is located at the intersection of the
following two straight lines:
The line through the following two points: The clock tower at Welch and Chamberlain; the second closest coniferous tree to the intersection of 6th and Hazel, only including trees that are west of Hazel.
The line through the following two points: The Janus Agri altar in the courtyard of Agronomy Hall; the commemorative sign to the "First Land-Grant Home Economics College" located about halfway down Osborn Drive.
Some knowledge of trigonometry is required to solve this cache.
Don’t round unnecessary decimal places – it may reduce the accuracy of the final coordinates.
The final cache site may require climbing, crawling, or a
similar physical endeavor.
Please replace cache as you found it. Thanks!
Cache is a clear tupperware container with blue and yellow lid.
Original Contents: Berlitz French phrase book and dictionary; CD carry case; spiced apple fragrance; gold-colored swan; vanilla candle; big clip
Notes for those from out of town – Maps of ISU showing locations of campus buildings are available on the ISU Website. Convenient visitor parking is practically nonexistent on weekdays, and the campus Parking Nazis give tickets frequently, but you should be OK just parking there for a few minutes, and there are plenty of spots on evenings and weekends. If you get a ticket, I think you can just send it in marked “visitor” and not have to pay, but I’m not sure about that.
