There are quite a few puzzle caches in this area, many of which haven given me a fair amount of trouble, and some that still are giving me trouble. After spending a lot of last winter at college working on solving them, along with some time this summer, I have finally gotten a chance to place my own puzzle cache.
Solving for the coordinates is nice and straightforward... you just solve a bunch of math, chemistry, and physics problems. These can all be solved using high school level physics, math, and chemistry. This does not mean they are all easy, but they should be solvable by those who aren't particularly science-minded, as long as you're dedicated and decent at Googling things. (Also, engineers, if you're using much calculus or other advanced concepts, you've probably overcomplicated things).
The coordinates are N42 AB.CD W83 EF.GH. D and H are both two digit numbers.
Light with a frequency of 7.21x1014 Hz has a wavelength of 4A6 nm.
B3 + 2B2 - 5B = 6
In triangle XYZ, angle X is 100°, angle Y is 30°, and angle Z is 50°. Side XZ is 6.3 cm. Side XY is 9.C5 cm.
A rocket launches with an upward acceleration of 20.83 m/s2. It has enough fuel to last 8 s. The rocket goes 2D2 m high.
A ball thrown at 6 m/s travels a horizontal distance of 3.3 m before landing at the same height from which it was thrown. It was launched at E2°.
At 60 °C, 2.6 moles of sulfur hexafluoride occupies 73L. Its pressure is F8600 Pa.
A satellite orbits the Earth at a distance of 7.57x106 m from its center. (1.19X106 m from Earth's surface). Its period is 10G minutes.
200 g of propane combusts in an excess of air. H7 g of water form.
I tried to write the problems so that slight differences in the constants used won't matter, but if you have a issue, contact me and I am glad to check your work.
I averaged these coordinates multiple times over several days, but still wasn't getting vary consistent results. Since placing this cache, there have been several logs about difficulties actually finding the cache. I went back in November 2017 and recorded the coordinates again. I didn't average the coordinates, but I did use two devices. These coordinates will be shown in the geochecker after you get the correct solution. I'm not sure which set of coordinates is better, but you can try both.
