In the progress of our journey down the River on the route of the old-time fur brigades, we have passed over what may be considered the first two stages of the stream. The first is the lagoon-like expanse of the section from Canal Flats to Golden, one hundred and fifty miles. The second is the more swift and turbulent part from Golden to Revelstoke, two hundred and fifty miles. At the latter place we enter upon a third stage of the River, the lake stage. The region of the lakes constitutes one of the most unique and delightful of all parts of the River. Let the reader consult the map and he will find an area of probably one hundred thousand square miles in British Columbia, Washington, Idaho, and Montana filled with lakes. This lake region constitutes a plateau, crossed indeed by mountains and somewhat rough in surface, but of a uniform general elevation. It constitutes a sort of debatable region between the two great slopes, one from the Rocky summits to the lakes and the other from the lakes to tide-water. On those slopes the white waters of cataract and rapid are found; on the plateau, the deep, still lakes. A glance at the map reveals the fact that the larger of these lakes are long and narrow, and lie on north and south lines. A journey on them reveals the fact that they are deep and clear and cold. Join these facts with the additional one that they are surrounded by snowy mountains, and you have no difficulty in deciding their origin. They are glacial. At some time in the glacial ages, stupendous ploughshares of ice descending from Rockies, Selkirks, Gold Range, Cascades, and Bitter Roots, gouged out profound canyons in the rents already wrought by earthquakes, and these became the lake beds.
