Go to the place with the Snowspeeders. Look on your map. Find a place with a large curve. Fly there and you will be in the area where the Wamaps are found, but all the objects will be gone. The places where the object was touching the ground will now be a hole. Fall in the hole. You will fall for about thirty seconds. If you fly into the place where the cave used to be, you will be under the ground.
