Flooded sinkhole

 is a location in Point Lookout.

The Flooded Sinkhole is a lake that separates the Trapper's Shack from the Grower's Shack. When you swim down to the bottom, tons of miscellaneous items float to the top. At the the bottom are three safes, a First Aid Kit and some barrels. Two Nuka-Cola Quantums can be found floating in the water here.
