If I remember right BWJ had a story years ago where some locals went in to see the pictos east of Montgomery Lake. It was a cold snowless year and they traveled the lakes on ice skates, via Pickeral, Buckingham, etc. If I remember right it was a day trip too. Probably set off from Stanton Bay.

From what I've gathered from experienced trippers, winter camping is best left to our off season day dreams, i.e. more fun thinking about than really doing. If done, and you really wanted to be remote, try riding a train in and hiking a short distance away. Return by train when you've satisfied your curiosity.
