All of Jack London's 'Yukon' stories are worth a read. I have seen some criticism of him, on the grounds he died a bloated alcoholic, by his own hand, and only spent a single winter in the Yukon.
Having said that;
The stories ring true. Much must be either personal experience, or first-hand account from someone else. Either way it's reliable.
There is considerable doubt that he killed himself. Lots about this on the web.
Anyone who stands a single winter in the Yukon, in [/i]fin de siecle gold rush conditions, deserves our respect. In my opinion. Especially after carrying a ton of supplies over the Chilkoot trail.
Agree Robert Service is also worth a read. Or better still, a read around the campfire, while the bannock bakes.........
