Fallout 3 locations project
The Deathclaw Sanctuary is a location in the Capital Wasteland between Dickerson Tabernacle Chapel and Broadcast Tower KB5. It can be reached by traveling southwest from Fort Constantine or south from SatCom Array NW-05a. As the name suggests, it is home to numerous deathclaws.
The Deathclaw Sanctuary consists of a single, large cave. There are multiple body piles and even a sizable pool of blood. The twisting tunnels and large obstructions are hazardous, but the residents make this one of the most dangerous places in the Capital Wasteland.
Outside of the sanctuary is a small overhang with many skeletons, presumably victims of the deathclaws. Further down the face of the cliff is a bridge crossing a large gorge. There are two smaller-than-average deathclaws guarding the entrance which will respawn every three days. If approached from the correct direction, a random encounter can occur.
After The Waters of Life, an Enclave camp will appear on the nearby cliff north-east of the entrance. This usually consists of a Tesla soldier and an Enclave Scientist, as well as a mind-controlled deathclaw and two Enclave crates.
When traveling to the Sanctuary from the west it is possible to fall into the gorge as it is hard to spot among the rocks. A high Perception level allows you to see the deathclaws on your compass and can serve as a guide.
The interior is a dark, maze-like cave complex which seems to serve as a nest for somewhere between six and twelve deathclaws. The sanctuary seems to function both as a nest and a storage place, indicated by the many piles of maimed bodies and body parts that can be found in specific places. Several wastelanders, raiders, mercenaries, and rotting brahmin corpses are among them. Many of the corpses will yield good loot.
 The Waters of Life
If the cave is cleared out before The Waters of Life, only deathclaws will be found here. However, after the arrival of the Enclave, a group of soldiers appear to have entered the caves to explore. This has an effect on the unique weapons found here, see the loot section. They spawn alive in the caves, but unless you cleared it out once before, they surely won't be among the living by the time you find them.
The Enclave probably set up camp here to test out the deathclaws' usefulness to the Enclave military operations. While venturing into the deathclaw-filled cave was not the brightest idea, the scientists outside have clearly managed to capture some specimens. The research appears to be a success, as one can encounter deathclaws with mind-controlling devices on their heads in other Enclave settlements (including Raven Rock).
 Notable loot
- There is a locked (average) footlocker right outside the cave entrance which contains a Duck and Cover! book along with other items.
- Bobblehead - Endurance directly south of the entry inside the cave, in the first large chamber - on a short pedestal near a pile of corpses and a rotting brahmin. (It is to the immediate left at the bottom of the entry slope, ground level)
- Nikola Tesla and You, a Nuka-Cola Quantum (located a few steps east of the bobblehead, next to a dead Enclave officer), and a mini nuke are near the bobblehead.
- Vengeance, in the far southeast of the caves, near some blood that is literally a pool.
- Jack, on a dead Enclave officer in the southern part of the cave (only after The Waters of Life).
The Deathclaw Sanctuary appears only in Fallout 3.
- The deathclaws that spawn around the entrance to the Sanctuary have been known to suddenly and spontaneously shoot up into the air. This seems to be caused by their spawn points placing them slightly below a surface they should otherwise be standing on, the resulting reaction of the physics engine seems to propel them skyward.
- The deathclaws that spawn near the entrance may also spontaneously die while fighting you.
- The deathclaws that spawn near the entrance may also fight each other. When one of the several that spawned die they will turn onto the player.
- The torso halves found in the pool of blood near the Vengeance have strange physics applied to them. Picking them up (either the legs or the torso) results in them spinning in midair—regardless of whether you are moving or not.
- The various deathclaw cages in the Enclave base outside the sanctuary have been known to only show the doors, and not the rest of the container. the doors do however still function.
- By the bobblehead, the rear half of a brahmin can be seen sticking out of the ground shaking due to it being stuck through the ground.
- The deathclaw that is walking at the pool of blood may not attack you.
- This area has a lower frame rate than any other place in the game, simply walking through it may cause you to drop to around 10 fps. However, the frame rate will often stabilize after the first room of the cave.
- An Enclave soldier can spawn near the Sanctuary when first approaching despite not completing The Waters of Life quest.
- The rotting brahmin has been known to be situated directly on top of the Endurance bobblehead making it rather difficult or nearly impossible to obtain. It is possible to move the brahmin with a Fat Man or other powerful weapon in order to acquire the bobblehead.
- There is a hole/pit that one can fall into, with no possibility of getting out. It is located near the southeast portion of the map.
