In spite of the many trips I've taken in the B-Dub and Q I have only heard wolves once, on LaCroix, while out camping.  I have a friend who goes to Basswood yearly; 2 of the past 3 years they have had wolves IN CAMP.  Once the wolves seemed to be casing the camp for left overs and once the pack chased a deer right through the camp.  When campers got thrown into the mix the wolves retreated and the deer swam away.  Other campers have also encountered the Basswood pack.
We live on the south western edge of the BWCA and have our share of wolves.  My husband used to go outside at night and howl for them...partly to drive the neighbors dogs crazy...but the wolves often answered once he got them started.  You could try "calling" them. 

Jim, that's exactly what I was telling him just last night - unnamed lakes are pretty close in (easy to get to from Bhouse), and going Wawiag seems so much more appealing - get through Greenwood, down W, and get a treat through the poet lakes then head back up to our familiar stomping ground through Lonely et al and out through Nym.

As for wolves, that makes sense about the logging areas - certainly all predators follow their prey, although I too have seen scat on many a portage throughout our trips.

Guess like it was said, you just gotta get lucky enough to be nearby when they decide to sing! I do believe dad heard them once on one of his 80's trips...one day!!
