Abandoned Shore Lines of Lake Superior. — Taylor. 367 
Sand River station. The belt of beaches varies in width from 
an eighth of a mile at Harvey to more than a mile at Sand 
River station. The Chocolay river flows westward behind 
them, close to the lake, for a distance of about four miles, 
that part of its course evidently being determined by the 
westward predominance of shore drift. In the case of the An 
Train river the bay reached so far inland that the waves failed 
to carry the sand up to its head, but built out spits which 
united across it, and the waves afterward built upwards of 
forty distinct beach ridges of sand, arranged in successive 
order from An Train lake, which was cut off in this way, out 
to the present shore. It is more than a mile and a half across 
these beaches. The process is still going on, as may be seen 
at the mouth of the An Train river. I had visited the Au 
Train country in the autumn of 1882. In the eleven years 
which had passed since then, I could see that there had been 
a distinct growth of the shore line outward. At the sides of 
the outer ends of these vallej's the shore line is plainly marked 
as a terrace cut into the drift. Lake Independence, Pine lake, 
and others along this shore, have the same origin as Au Train 
lake. At Old Munising, near Grand island, this beach ap- 
pears again as a very sharply defined terrace of coarse white 
sand, about 200 yards wide and 25 feet above the lake. Frag- 
ments of it were seen still farther along the shore in clefts of 
the Pictured Rocks where small streams enter. Eastward the 
shore was not seen, but it is well known to be very sandy, as 
would be expected if it is bordered by the Nipissing beach. 
Beginning at Light House point in Marquette, this same 
shore line passes through the northern part of the city and is 
finely developed in that locality. It is there composed of a 
series of sandy gravel, shingle ridges, the highest passing 
along the foot of a low blurt' from which it is separated by a 
lagoon hollow. From Hewit avenue east of Cedar street the 
bench extends about a mile and a quarter due northwesl 
through the city. The abandoned sea-cliff is well developed 
at the corner of East Prospect and Spruce streets, and at 
that point there was a small rocky island close to the cliff. 
At the corner of Third and West Hematite streets the upper 
ridge with lagoon hollow and low cliff is crossed by the 
Presque Isle Park electric cars. A third of a mile beyond
