Forest Grove marsh is a location in the Commonwealth in 2287.


Half of the town is flooded with irradiated water and inhabited by feral ghouls. There is no loot of consequence in the flooded portion of town except the mutated fern flowers which Solomon asks the Sole Survivor to gather in the quest Botany Class. Opening the pub's door near the water on the side of town activates a frag mine.[1]

There is a collapsed, two-story gunshop near the northwest corner of the town. It can be identified by the flashing red light and tall antenna on the roof of the building. On the second floor of the shop are a weapons workbench and duffle bag. On top of the roof are a steamer trunk, two sleeping bags, supplies, and Sheila's holotape. To the east is a house and garage with a white Pick-R-Up in the driveway. In the garage, there is evidence of a suicide.

Behind the scenesEdit

Forest Grove marsh is based on the real world location of Forest Grove Park in Waltham, Massachusetts.



  1. Fallout 4 Vault Dweller's Survival Guide p. 314: "Forest Grove Marsh is a series of residential and other small buildings that have sunken and been flooded by the river. Some radioactive leak below the area has irradiated the water, and though scavengers have tried to put up walkways across the rooftops of the buildings to explore the houses, the numerous Ghouls in the area have stopped all but the most inquisitive or reckless scavengers. Proceed at your own risk."
