Ahoy, mateys!
History may tell ye Captain Blackbeard and his ship the Queen Anne's Revenge never sailed as far west as California, but if that be true, how did I find his booty? Aye, it's a fair mystery. I lost the treasure map that led me to his hiding place, but I recall where it was hid well enough to guide ye there. Once ye get to the right spot any able seaman should be able to find it yerself without any trouble. On a fair-weathered day, it's a 0.10 mile hike from the trailhead (that's 0.087 nautical miles for the true sailors among ye).
Take care with the cache host as it be fragile and well-guarded by thorns. Untwist the ends of the cord to retrieve the treasure chest, and take care to hide it better than ye found it or I'll make ye walk the plank! And remember, if ye take some of Blackbeard's treasure, leave yer own loot behind so the next crew has something to find.
