Modoc caves are a part of Modoc.
These caves are under Modoc - goo from the toilets are dropped here. Also, a lone mole rat lives here.
- To gain access to the mole rat, Chosen One must place some explosives (like dynamite) and climb up. After that, Chosen One might suffer some damage and Rose's Bed and Breakfast part of town is filled with goo.
- If examining a part of the goo (near the tunnel), a note will appear that there is much amount of goo making the computer very difficult to access - a note similar to the computers in the Los Angeles Vault.
Modoc caves appears only in Fallout 2.
