Although the cache type is "Puzzle", the cache IS at the posted coordinates. But before starting this hunt, you really should read up on Archimedes. You will easily find WHERE this cache is placed - in fact, you can see the hiding spot from hundreds of feet away. However, retrieving it (and doing so without being observed) may prove as taxing a challenge as Archimedes was given by King Hieron. Once you succeed, maybe you'll also cry "Eureka!"
You see, you won't be able to reach it without the right preparation. You don't really need any tools - it will come right to you if you pour some effort into your homework. So - what're you waiting for?
The container itself is a very lightweight, clear plastic tube about nine inches long and one inch wide. There is no room for any trades (please don't add any) although a pen is provided. And there's no way to grasp the container; no tools will work. So you'll need to be as creative as Archimedes. By the way, please don't use force! The tube can break easily and ruin the log. Trust me, you don't need ANY tools. But without the right preparation, you will NOT get this one. Although you don't need tools, you WILL need to have something specific with you. Oh, and PLEASE don't post spoilers in your log.
