42 A. S. Packard on Glaciers in the White Mountain Valleys. 
Art. VI.— Evidences of the existence of ancient Local Glaciers in the 
White Mountain Valleys ; by A. S. Packarp, Jr., M.D. 
ders of a peculiar mica slate, enclosing crystals of staurotide, 
which had evidently been transported from near the summit of 
Mount Washington. ‘The summit of Mt. Kearsage we found 
moulded by ice. Dr. C. T. Jackson in his report on the Geology 
of New Hampshire states that the drift scratches one half way 
up Mount Kearsage run N. 80° W. He also states that on 
Mount Chicorua they run N, 35° W. (S. 35° E.), which is the 
course of the Ossipee valley just below it. 
On a hill just east of Goodrich’s falls on the Ellis river are 
very distinct ice-marks, on polished surfaces, with strize running 
N. 30° W., and lunoid furrows with their horns pointing up the 
valley in the same general direction as the grooves. 
Crossing over the mountains into Chatham, and Stowe, Maine, 
into the valley of the Cold river, another tributary of the Saco, 
we find another set of strie. The broad summit of Speckled 
mountain, opposite Mt. Royce, which two mountains guard the 
southern entrance of Evans’ Notch, is glaciated both on the N.W. 
and N.E. flanks. Here also is a ‘‘col,” down which the ice must 
have moved in both directions, Near the summit the grooves and 
lunoid furrows run N. 15° E., following the course of the valley 
at this place, and aiming at a higher peak to the north and east. 
On Mt. Baldface, 3600 feet high, three or four miles southward, 
the grooves are very clearly indicated both below and directly 
upon the summit. Here they run N. 10° W., and it might be 
mentioned that the Cold river valley turns more to the southeast 
at this point. On a shoulder of the mountain, perhaps 300 fees 
below the summit, the lunoid furrows are especially abundant. 
On the summit of this mountain, which is made up of a light 4 
colored fine syenite, were a few boulders of a peculiar eo cegee q 
- Sie with oblong crystals of albite. Following the N. 1 
’, course, less than a quarter of a mile, we
