Near Ashton in Fremont County, Idaho — The American West (Mountains)
The Three Tetons
Perhaps as early as 1819, French-speaking trappers were calling them the Trois Tetons - - the three breasts. More prosaic English speaking mountain men named them the Pilot Knobs, but the romantic French name stuck. This is one of the finest views of the peaks from the west, the side from which they were seen by the men who named them.
