Lake Mead Cave

The entrance to Lake Mead Cave is underwater. Northeast of Ranger Station Alpha on the other side of the lake is a partially submerged boat. This boat is red and the bow is sticking out of the water. By swimming under the boat on its west side you can follow the cliff down to the cave entrance. This cave is just a touch southeast of the Crashed B-29. The easiest way to find it is to go to Callville Bay. There is a boat ramp that faces southeast and has a nonoperational harpoon gun. Follow the angle of this boat ramp and swim out into the lake that direction, pass over the bomber to get to the cave.

Loot
Just inside the cave are a few ammunition boxes and a Sunset Sarsaparilla crate. Exploring further in might prove difficult without the rebreather, as the rest is under water. If you do however, you will find a skeleton with three suitcases full of pre-War money and another ammunition crate with the very rare .45-70 Gov`t(sometimes, another player merely found 30 energy cells and 3 missiles, and yet another found 11 10mm rounds and 83 Flamer fuel, and yet one more person found 8 .357 Magnum rounds and 74 Electron Charge Packs) in it. Also, you can find a Lad's Life magazine near the suitcases too.
