I am taking my kids to Lac La Croix next week.  We have a BWCAW permit only.  Do we need another permit to see the pictographs and Warrior Hill?  If so how do I get that permit?

Also can anyone recommend a book that contains information about the pictographs and Warrior Hill.

I have a vague understanding about Warrior Hill, but does anyone have information about the "legend" or stories of W.H.?  I have found that this kind of information really is enjoyable to my kids....

Thanks
