All the directions for the spots, are assuming you are standing in front of,
and facing away from Jim WaveMonger (and the cavern wall).
One dig spot to the left next to camp, just a few feet away, its actually 'in the camp' on the edge.
Further to the 'left', is an island like area with a scorpion in the far corner. There is a dig spot
in front of this scorpion, its a little ways out, but its always been there (close also to where the 'bridge' connects to the same piece of 'land').
Ahead of you there are 2 Navy guys talking in a path crossing area. There is a dig spot across from them, they will not bug you while you dig there. Walk into the area, stay right, search right side of the clearing they are in.
And as mentioned before, you can keep re-searching the same spot, and it will eventually cough it up (well usually).
