The Black Mountain Ordnance Works is a fascinating location in the vast world of Fallout 76, situated in the west central area of Appalachia. This hazardous containment depot is nestled north of Point Pleasant and south of Transmission Station 1AT-U03, within the Forest region of Appalachia. While it is not directly associated with any main quests, the site offers intriguing lore and hidden secrets, making it a compelling destination for explorers.
Layout and Enemies
Upon arrival, players can expect to encounter Feral Ghouls and Liberator Bots, which are common enemies in the area.

Inside the bunker, players can find scrap materials and ammunition, along with a terminal that provides insight into the facility's past operations.
The TNT Domes
