you should try to get hold off a book from the 70s called "The year long day" absolutely brilliant book about a guy who lives in a cabin in the arctic circle and lives by hunting the trap lines.
Its so easy to read and is funny at times, he has run ins with polar bears and befriends a arctic fox for company.
will get hold of the author for you later mate
Colin
EDIT "Ivan Rudd" is the author i believe.
