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.
Mass Gravel & Sand appears only in Fallout 4.
PC 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.
