This cache was inspired from the pirates! This is a puzzle barrel (because the pirates made puzzels and riddles? You know what I mean, nvm)
Cache is at posted coordinates and is a field puzzle. This one may be difficult. My first time solving took over an hour to solve but then again maybe that's just me being dumb. Just be prepared to have a good chunk of time to solve. Once you solve you will need to do the puzzle in reverse to lock it back up so try to remember your moves.
This puzzle works with a screw that lowers/raises a center peice that rotates using your fingers to spin it. There are 3 moving parts that must leave the barrel to access it, 1 screw "key", and 2 locking mechanisms. If the screw doesn't wanna screw anymore, don't force it, it can break, it clearly isn't the right way. If you already completed this type of puzzle before then it should be similar to do and can complete in a minute or two.
The barrel is on the EAST side of UNDER the bridge, you will need to climb a short platform to reach it (only about 3 feet up). The barrel is passing into a neighborhood but they are aware of the placement so you shouldn't be bothered. Be careful of going after a storm or when snow is melting as water will be flowing but it isn't much. Please visit during evening/night to avoid being seen.
Congrats to hartsdale for FTF!
