Note 282 — NARRATIVE OF A YEAR'S RESIDENCE AMONG THE INDIAN TRIBES OF THE ROCKY MOUNTAINS
Reading edition
Part of the Great Plain of the Columbia, broken by many fantastic shapes of the volcanic underlying rock. Most notable of these is the Grand Coulée, which, however, De Smet did not cross, for it lies north of Spokane River. He probably took the trail afterwards developed into a part of the Mullan road, from Great Falls of Missouri to Walla Walla. From the land of the Cœur d'Alène he returned along the route by which he had come out—the St. Regis Pass and river St. Regis Borgia.—Ed.
