This fork occupies a relatively small valley, which does not head at the crest line of the range and which was not glaciated. There are moraines adjoining this valley, but they are associated with the larger valleys to the east and west. Next to Middle Fork of Sheep Creek on the east is East Fork of Sheep Creek, which flows in approximately the same direction as Middle and West forks. This fork occupies a glaciated canyon. Its basin contains two large cirques and its canyon has the characteristic U-shaped form. The outermost moraine is located near the place where the Government road" crosses Sheep Creek, at a distance of about 7 miles from the crest of the range. East of this moraine (t The Government road crosses the range near the eastern margin of glaciation and is a most convenient feature to refer to in locating certain of the glacial formations. (See PI. IV.) there is considerable outwash material, which in part follows the course of the stream as a valley train and in part spreads out eastward as an outwash plain over a broad meadow land. The outwash and terminal moraine material was derived entirely from the quartzite of the central portion of the range, for the ice, even at its maximum extension, did not advance beyond the outcrops of that formation. The terminal moraine has a pronounced ridge at its outer margin, but immediately within that ridge the topography becomes hummocky. The stream has cut its way through the terminal moraine at the northern margin and now flows between the morainic hills at the right and a hogback ridge of red quartzite at the left. The quartzite formation at this outcrop is a fine grit. The stream appears to have shifted laterally until it reached th...
