Mass Gravel & Sand is a location in the Commonwealth in 2287.


This small quarry just north of Cambridge is a lookout for raiders and a habitat for mole rats.[1]


A small gravel operation consisting of two silos and a two-story watchtower with only the second floor being accessible. Inside, there is one raider, a weapons workbench, and minor loot. Mole rats (possibly different variations) usually spawn here. Several wrecked cars are around the area and may explode during a firefight. The silo in the center of the area has a duffle bag hidden at the very top.

Notable loot

There is a suit of power armor in a locked security cage at a military checkpoint just a short walk due east via an Advanced computer terminal.

Appropriation: One potential destination for this quest may be a small shop building west of this location.


Mass Gravel & Sand appears only in Fallout 4.


PCPC Companions such as Hancock may, when entering the upper floor of the tower, comment about the raider's actions even if the raider was not present when clearing the location.[verification overdue]
