Toxic caves

The Toxic Caves is north from Klamath. Before the war it was a military warehouse of some sort. Now it's a radioactive cave inhabited by Geckos (little and gold). Some good equipment can be found there provided that you have a set of Electronic Lockpicks. Also Smiley, the trapper from Klamath, is waiting there for you to save him.

Ms. Buckner will put the Toxic Caves on the map once you take the Save Smiley from toxic caves quest.
