Sorry…the posted coordinates are NOT the location of the cache. I really didn't want to make this a mystery cache, but due to the proximity of the highway and prison it was the only safe option. But don’t run away puzzlephobes! You don’t need to be rocket scientist to solve this one! With some close attention to all the details, the solve will click... even for a space cadet.
While the coordinates are NOT the site of the cache, they do mark the approximate location of the discovery of “The Oshkosh Meteorite” – the only known find of this kind in the area. The story below is about the meteorite and it’s discovery. It’s a perfect lesson for geocachers…You never know what surprises you’ll discover if you keep your eyes peeled when looking for something else.
In the fall of 1961, Ronald C. Meyer of Appleton was a college freshman at what was then known as Wisconsin State University, Oshkosh. On September 17th, he decided to hitchhike down Highway 41 to spend the weekend at home. As he waited for a ride near this spot, he passed the time by picking up stones and tossing them at the nearby billboards. As he picked up one of the rocks, he noticed it was different. It reminded him of the fragments of a meteorite he had seen at an exhibit at Lawrence University when he was in high school the year before. He put the fragment, along with others like it he had found in the vicinity, into his pocket. Upon reaching home, he immediately mailed one of the fragments to Professor William F. Read of Lawrence University’s Geology Department where it was confirmed…Mr. Meyer had found fragments of a meteor. On September 25th, Mr. Meyer took Prof. Read to the vicinity of the find to search for additional fragments. Unfortunately, additional and future studies only yielded one additional small fragment and no witnesses to the entry, known as a fall, were ever found. A 1-gram fragment was given to the American Museum of Natural History for study. The remaining fragments were reported to be deposited in the U.S. National Museum.
About the meteorite: A total of 12 fragments weighing 144.8 grams were discovered between Mr. Meyer and Prof. Read. At the time, the fragments were identified as an olivine-bronzite chondrite. Today, these are officially known as H chondrites. H chondrites are part of the ordinary chondrite family and have higher iron contents and smaller chondrules than the other types of ordinary chondrites, L and LL. About 80% of all meteorite falls are ordinary chondrites with about 40% percent of them considered H chondrites.
Using math to find the cache: (for those who want to do it the hard way)
A = Amount of days between the first discovery and the secondary search.
B = Number of fragments picked up in the initial discovery.
X = Number of ordinary chondrites classifications that are NOT H chondrites.
Y = Percentage of all meteorite falls that are H chondrites.
For the new NORTH coordinates:
• Add A times B to the last three numbers of the given North coordinates.
For the new WEST coordinates:
• Add X to the 2-digit number on the LEFT side of the decimal in the given West coordinates.
• Take Y% of the 3-digit number on the RIGHT side of the decimal in the given West coordinates, double that number and round down to the nearest whole number.
For anyone who really feels the need, check your math here.
Take care with discovering, retrieving, and replacing the cache to save the experience for others. Spoilers in the logs will be immediately deleted. Thanks for your understanding…and Happy Hunting!
NOTE: The final is placed along the Wiouwash Trail. Geocaches placed on Wisconsin Department of Natural Resource managed lands require permission by means of a notification form. A Geocache Notification Form for this cache such as the completed one here was not submitted to the office of the Wisconsin DNR because the section of the trail is actually managed by Winnebago County. Anyone interested in placing a cache on lands managed by the Wisconsin Department of Natural Resources should fill out a blank DNR Notification form which can be found along with the land manager information on the WGA website. Print out a paper copy of the notification form, fill in all required information, then submit it to the land manager before placing your cache.
