What is the setting for Gary Paulsen's The River?

The River, a sequel to Gary Paulsen's
best selling novel Hatchet is another story of Brian Robeson's
survival in the Canadian wilderness.  Rather than surviving a plane crash in some remote
wilderness setting, at the beginning of this story, government officials approach Brian
with the idea that he will go back to the wilderness (with a psychologist) and show them
how he survived.  This information will then be used for survival training
purposes.

The setting, never named specifically, is a
specifically chosen, remote wilderness location in "northern Canada" on a lake.  At
first, the idea of "survival" seems silly to Brian, who notes that the location does not
provide much in the way of a challenge.  There is also a river which flows out of this
lake, which becomes the setting for the bulk of the action in the story.  After a
lightning emergency, Brian ends up building a raft and floating this river over 100
miles to seek help.

Much like Hatchet,
the wilderness setting is key to the development of the plot.  Brian makes mental note
of many key details in his surroundings, which of course, is key to his
survival.
