Cass Timberlane, A Novel of Husbands and Wives by Sinclair Lewis

There was as yet no wartime gasoline rationing in the Middle-west, and they had driven, for the beginning of their summer vacation, north to Ely and the deep woods of the Arrowhead canoe country, up to Grand Portage, which in the 1790's was the castle of the French and British fur traders. You can still see the ghosts of the voyageurs, in capotes and sashes, toting their canoes at twilight.

They drove back along the vast bright palisades of the North Shore of Lake Superior to Grand Marais, and up the Gunflint Trail to a dark lake curtained with pines, where they paddled under a great sunset that made their voices cleave together in fear of loneliness, beneath that threatening majesty.
