Where is the poacher camp in cabelas outdoor adventure?

If you open the map of the area, you will see that there is a little island off the southeastern tip of the eastern landmass. Travel until you are directly West of the island. Then continue West.

You should see it before you reach the other side, or even before you reach the island in the first place.

The most prominent feature of the poachers' camp is a large, basic wooden structure on the northern side of it.
