Sea cave

The sea cave is a location in Point Lookout, entered through the wrecked seatub or the well outside the Ark & Dove cathedral. Tribal leader Jackson uses the cave to communicate with a hologram of Professor Calvert.

Layout
The cave consists of a series of passages leading to a main chamber, where Jackson communicates with Professor Calvert. The sea cave is inhabited by swamplurks, mirelurk hunters, and swamplurk queens. Additionally, a lone unnamed friendly tribal wanders the cave and will follow the Lone Wanderer around if he spots them. However, the tribal will often be killed by mirelurks before being encountered.

Loot

 * The sea cave contains the largest amount of pre-War money in one location in Fallout 3 at 39 stacks; 14 are found in a half-sunken rowboat, and 25 are found in and around a chest with a mattress.
 * 11 Confederate hats can be found on the floor of the grotto where Jackson is found.
