"The chief purpose of this book is to put into proper perspective the historical significance of the valley which long acted as a funnel in bringing settlement into the great empty lands. Its entry point was at Fort Okanogan, a point on the Columbia River at which fur traders had seen fit to install -- not one, but several -- posts and forts. I have tried to delineate the geographical facts attendant upon this Great North Road, or the Okanogan Trail, but its many fascinating turns entail a wealth of human narrative which might obscure the bare bones of history."
