Following the Great War, mining operations and visits from tourists have long stopped, and evidence of the mine's use as a storage location for barrels full of radioactive debris can be found. Two centuries later, the long-abandoned mine is used by the Legion under Decanus Alexus to hold captured NCR troopers.
The mine is located at the turnaround point on the road past Nelson and was used as a dumping ground or storage area for nuclear waste. There is a hollowed-out rock directly to the right of the mine's entrance. The rock is marked with two white rectangles. After a short winding path from the entrance, there is a small chamber containing Legion troops, and paths leading left and right.
The left path leads down to a large, irradiated chamber with a group of eight Legion members including their leader Alexus, who holds the key to the storage areas down the righthand path containing NCR prisoners. The chamber centers around a large concentration of irradiated barrels and over a dozen skeletons lying among the waste.
Farther down the path, there are two Average locked gates with various weapons and armor within. Taking the righthand side path leads to a small chamber with four Legion troops and two locked storage areas, each containing a tied-up NCR soldier and some loot.
- Anywhere I Wander: The Courier is approached by Private Renolds who has escaped Legion captivity in the mine. He asks for help in rescuing two other NCR soldiers who are still held captive.
Techatticup Mine appears only in Fallout: New Vegas.
Behind the scenes
When approaching the mine, the troops outside (or even inside) will not attack the player character, even if being vilified by Caesar's Legion.[verified]
- Fallout: New Vegas Official Game Guide Collector's Edition Tour of the Mojave Wasteland: Techatticup Mine, p. 419: "Also known colloquially in the past as Knob Hill Mine, this hole in the ground is at the turnaround at the end of the road from Nelson, and seems to have been a dumping ground, or storage area for radioactive waste that the Legion now occasionally utilities. Along the road, you may meet Private Renolds, talking about "that bastard" Alexus; a Legion commander who's take his squad hostage. This begins Side Quest: Anywhere I Wander, but you can free (or ignore or kill) the NCR in here without running into Renolds. Check the Hollowed-Out Rock at the entrance before proceeding."
