This cache is not at the posted coordinates.
First, find this building, 0.62 miles from the posted coordinates, somewhere on the island.
Nothing is hidden near the building itself. However, once there, figure out how to reorder the 6 digits shown in the photo.
Those 6 digits, in that order, complete these partial coordinates for the cache, not too far away: N 40 46.??? W 73 55.???
