On the 14th of September the party reached the heights of the Rocky Mountains, safe and in good spirits after many hairbreadth escapes, and drew near to the Pilot Knobs or Trois Tetons, that great landmark, so singular and conspicuous, near which is the romantic source of the Louis River, or the great south branch of the Columbia.

The Three Tetons are the most noted historic peaks in the Rocky Mountains. The topography of the country is such that the highest peak, Grand Teton (13,691 feet) can be seen from a great distance and has long served as a landmark to trappers and pioneers. Unlike the mountains of that region, the Tetons are not hemmed in by foothills, but rise in bold relief from the surrounding plateau - the Grand Teton towering seven thousand feet above Jackson Lake, at its base. The range is but sixty miles long and lies some twenty-five miles southwest of Yellowstone Lake. It is crossed by Teton Pass, about twenty miles south of Grand Teton.
