Layout
As you first enter, you will see an entire over view of the cave, with a path leading down towards the first area. This area is populated by a small number of Tunnelers. you will see a fallin pillar and rubble forming a sort of wall ahead, through the hole in this is the second area of the cave, When you first enter, the Queen tunneler and many other tunnelers will spawn and attack you. Approach with caution and a loaded gun.

Notable loot
With the Wild Wasteland Trait, you can pick up a unique item: Dog Statue: Seymour. When you go into the cave, go straight. Look for an old world flag and follow the path behind a boulder. On the ground, very close to the statue is Sunflower Summers' Diary.

One of the Eyebots for ED-Ecated is located near here, just as you blow up the warhead head a little left and its on the ground.
