Abstract

One of the most highly deformed metamorphic rock series in Montana is exposed fifteen miles north of Yellowstone Park, Wyoming in the great gorge known as Yankee Jim Canyon, which was formed by Yellowstone River at that point. These metamorphics are Pre-Cambrian in age, and are almost certainly sedimentary in origin, although the involved and intricate folding which they have undergone has long since obliterated any superficial traces of that origin.
