This mine was the site of the Monongah mining disaster of 1907, killing over 300 workers. By the late 21st century, the mine was largely exhausted, depriving the town of Monongah of its primary source of work and income. The coal mine was rented out by the township to Hornwright Industrial Mining Company in 2075, in return for royalty payments until the mine ran dry. While the town hopped on the chance, Hornwright had no intention of paying these royalties for long and committed a substantial number of auto-miners to excavate the mine's remaining coal deposits under the supervision of Deke Sykes. Once the deposits ran dry - and they quickly ran dry with the auto-miners exploiting them at full power - the corporation simply packed them up and prepared to move on, ignoring the plight of the now impoverished town.
In January 2076 when the mine had run dry, locals and former miners from Monongah had rallied at the entrance of the Monongah mine to steal equipment. As Hornwright Industrial prepared to leave the mine that January, Earle Williams, and some other townsfolk drunkenly decided to steal some supplies from the mine before everything was taken away. However, while they were deep in the mine, the supervisor Deke Sykes blew up the entrance trapping everyone inside.
Some family members, such as Maggie Williams, attempted to clear the rubble with their bare hands, but a cover-up was already underway by Hornwright Industrial. Family and residents of Monongah were told everyone that was trapped in the mine had left town, an effort to avoid liability for trapping residents inside the mine and to avoid paying for an expensive rescue mission.
In the mine, Earle Williams and the others were facing a difficult decision: there was no food in the mine, but one of the miners, James, died from injuries sustained from the entrance collapsing. Several survivors agreed to cannibalize his corpse, including Williams, though others refused and stated they would rather die and be eaten than eat another person. Earle Williams questioned whether it was right to eat the corpses of those that starved, but being trapped in the mine left him and his other cannibals with little choice. Trapped in the mine with no sense of night and day further disoriented his senses and wore on his sanity. This gradual decline became a slippery slope for Williams as he would then partake in the consumption of people that had not died of natural causes.
By 2103, the Great War coming and going, Earle Williams had undergone full wendification. He, along with two others, had fused into a wendigo colossus. But Earle's daughter Maggie had not forgotten over the past 27 years, and is looking for help from some people to recover what might remain of her departed father, not knowing of what he has transformed into.
The mine complex has been turned over by the raiders but is otherwise remarkably intact. The loaded Hornwright flatbed remains parked in the center, surrounded by trailers used by the miner crews while the mine was still operational. There are no crafting stations here, however, and the mine itself is inaccessible due to a landslide over the entrance. The worker housing up the hill to the north is all boarded up and has only minor loot.
One part of this location contains an expert-level safe. As noted in the safe note, the key is the garden gnomes. The key to this safe is in the middle of three blue garden gnomes, found on the roof of a destroyed bus.
The mine's interior consists of a long tunnel which ends up prematurely in a large cavern, a horizontal mine shaft leading down into an even larger cavern and a sloped tunnel leading back up to the first cavern.
The tunnel is caved in at several spots, forcing a detour after entering the mine. To the left is an inaccessible door to a room with a trunk and several junk items. The room becomes accessible during the event quest. To the right is a small changing room with some metal lockers, a tinker's workbench, and a chemistry station. The door next to the chemistry station leads to a small restroom, where three quantum bears can be found in a sinister position. The path left of the tinker's workbench leads back to the tunnel which in turn leads to the first cavern.
The first cavern contains several workbenches, a couple of malfunctioning extractors on the sidewalls and a blue Hornwright Industrial trailer in the middle. Several defunct auto-miners are also present. The horizontal mine shaft is located on the right-hand wall, the rubble blocking it will disappear after five minutes have passed during the event quest.
The second cavern is located underneath the first and is reached by dropping down the mine shaft. It is home to many wendigo spawns and their overlord. It contains more malfunctioning extractors, defunct auto-miners, and some human corpses. On the far left wall is an exit in form of a long sloped tunnel, that is blocked by rubble until Earle Williams is dead and leads back up to the first cavern.

- Vault 76 resident: "How did he end up in Monongah Mine?"
Maggie Williams: "He and some other townsfolk got some liquid courage one night and decided to go up to the mine. I knew that damn bourbon would be the end of him somehow. They kept goin' on about getting the last of what they could before that Deke Sykes from Hornwright Industrial closed up the mine. Well, that son of a bitch ended up blastin' the entrance closed with everyone still inside."
- Vault 76 resident: "Why didn't anyone try to get them out?"
Maggie Williams: "You don't think I tried?! I clawed at the rubble until my hands bled and they had to drag me away. They told me that my pops ran off, and said the others left Monongah since there was no more work. I think it was some sort of cover up. They either got paid off by the Hornwrights to keep quiet, or they didn't want to deal withe the expenses of a rescue mission."
