Traveler's Hole

This otherwise normal sinkhole has one very odd property: every now and then, when someone dives in, they end up in some other body of water in another part of the world.

Thus far, no one has been able to solve the mysteries that surround the hole. There is no widely accepted reason for this effect to exist here. No one has been able to predict or influence where the teleporter goes and there seems to be no pattern as to when it will activate. The few people who have dived into the hole and were teleported claim the effect is nearly instantaneous and in no way harmful.
