Many years ago, when I was a Boy Scout, we were taught how to communicate using flags. In order to determine the real coordinates for this cache, you will need to solve the following puzzle, which uses this type of code:
The code is not difficult, but you may need to do some quick research on the internet.
You are looking for a camo'ed film canister. The cache contains a log-only; you will need to bring your own pen or pencil. There is no room in the cache for trading items.
Due to tree cover, you may have trouble getting precise coordinates, but if you use your geosenses, you should have no problem finding this cache. As is frequently the case with caches hidden in the forest, be on the lookout for poison oak!
Since the cache is in a popular hiking/biking area, please be sure to carefully rehide the cache, so that it does not get muggled!.
Since the challenge is intended to be the puzzle and not the find, I've added the following spoiler photo:
