Great Khan Supply Cave

 are unmarked locations in the Mojave Wasteland, two of which are located almost directly north of Bitter Springs. Inside the first are several Night stalkers and down a short passage there is an easy locked gate, behind which are a couple of Ammunition boxes and the quest item Great Khan Supply Cache.

The second cave is close by (left of the path leading to the first cave), faces the camp, and radioactive. 4 Giant Soldier Ants and 3 Giant Worker Ants guard an Irradiated Great Khan Supply Cache which is located at the back of the cave behind a fence the ants have destroyed. The Irradiated cache can be turned in to Captain Gilles at the Bitter Springs camp as a quest item, if you have 25 Science can advise to filter the radiation through Rad-X. You can also lie about the cache being irradiated for a karma (faction?) loss.

Additional unmarked supply cache caves exist, such as the cave containing Oscar Velasco.

Layout
The first cave's layout is very simple, a large, open room containing several Night Stalkers, with a small passage way leading to an easy locked gate, behind which are a couple of ammo boxes and the quest item Great Khan Supply Cache.
