Cache is a camo'ed metal water bottle. Enough room for very small trinkets only. Extraction tool may be needed for the log. To find the real coordinates.
Make 10 dots on a piece of paper, then put those dots in 5 rows with 4 dots in each row, not to exceed 10 dots total. (YES IT CAN BE DONE!) Count the number of letters in the resulting geometric shapes name. Take that number and subtract one to get the true last North coordinate. Take the original number (Geometric Shapes name) and add two to get the true last West coordinate.
Good luck on this one. This is my first Puzzle so I made it fairly easy.
