It is a dock which contains the home of a scavenger. This makeshift home consists of an upside down boat leaning against a tree with a bed and a footlocker under the boat.
- The scavenger can sit down on the dock, but the player can't, as it is an non-player character animation.
- After the Lone Wanderer completes the quest Those!, a leveled super mutant fighting 4 mole rats will appear nearby and may attack the scavenger.
- This specific scavenger is generic in-game, but identified as "Potomac fisherman" in the GECK.
The scavenger's dock appears only in Fallout 3 as an unmarked location.
