I know this is an old thread but I'm interested in reviving it because when I was a teenager in the 70s I did a 28-day trip that included White Otter/Turtle River.  This was before it was a park as far as I know.  Besides that trip I was on White Otter, Marmion, and other lakes in that area a few times in the early 70s.  Haven't been back since 1975, so I'd love to hear more about it now and maybe plan another trip there in coming years as an alternative to Q.  Bill
