Cache is NOT at the posted coords. Solve the puzzle to figure out where it really is. And I hope in the process you'll be surprised when you finally do.
Don't let this puzzle scare you!! Some cachers may be able to solve this the moment they see it -- or at least know how to. Others will have to do some research. Both Google and Donatello will provide the help you need. Something in a C.S. Lewis novel might help as well as you search for the BEST interpreter. DON'T use your smartphone to come up with the solution -- I can almost guarantee it won't work. The bigger your screen the better.
I'm trying this as an experiment to see how well it works. Brute force MAY get you what you need, but where's the fun in that? When you finally know what to do, and if things aren't working out, try changing the value after the ' "x ' in the first line from ".5" (that's decimal point 5) to something else, probably smaller (i.e., .3 or .2). If you make that change, you may also want to tweak the value after the ' "sx ' in the first line from -500 to something else, probably larger (i.e., -500 to -400 -- and yes, -400 IS larger than -500). DO NOT CHANGE ANYTHING ELSE!! Fair warning!! I'm guessing that I've done about 97% of the effort to solve this (and it took me quite a while to get this far) -- I leave the last 3% for you. No need for a geochecker on this one.
Here's a good hint, although maybe a bit confusing for those NOT in the know:
