Like I said in my previous post, when you find a withered tree, just walk up to it and press X then you should have the option of cutting it down. If you've already cut it down, then you obviously won't have the option of cutting it down. Once all six trees are cut down, a new road will open up to an area called, "The Tracks of The Beast". When you enter the area, you will find one of Montblancs clan members there. He will tell you whether or not the Gil Snapper is there. If he is not there just exit and re-enter the area until he says he's there, and he will help you take him down.
