X7ti The American Geologist. June, 1894 
remnant of a gravel ridge in the railroad yard which may be 
a fragment of a beach. So little of it remained, however, 
that no certain inference could be made as to its previous 
form, and there were elements in its composition which are 
not characteristic of a beach in that situation. Most of the 
pebbles were well rounded, but there was a good sprinklingof 
angular ones and a good many boulders of considerable size. 
A number of curiously cracked or sutured boulders were 
found in this bank. The altitude of this gravel ridge is 
about 600 feet above lake Superior. Following the road 
northeast about twelve miles towards the old Copper Cliff 
mine we found very little evidence of submergence, only a 
few terraces related to small streams. The best one of these 
is at the foot of the hill beyond Allouez. It is a very distinct, 
terrace and seems to be related to a plane of still water ex- 
tending northwestward over lake Superior. Two or three 
more terraces of this kind were found about two miles farther 
northeast similarly related toother small streams at about the 
same level. Their altitude above lake Superior is about 400 
feet. Although no certain shore lines higher than these wen- 
observed on the peninsula, it is doubtful whether they mark 
the upper limit of submergence. Neither the ridge at Hough- 
ton nor the terrace at Allouez has that composite form which 
marks the upper line at other places along this coast. 
Keweenaw Point. Our opportunity to visit the coast of 
the outer point came through the kindness of Messrs. Ralph 
and Arthur Cpnnable, who invited us to join them in a cruise 
on their fishing tug, the "J. W. Parmelee." We found several 
fragments of beaches on the outer point above the level of 
theNipissing beach. There are faint traces of a beach about 
75 feet above the lake back of the copper smelter at Lac la 
Belle. On the western slope of Mount Bohemia I found nar- 
row terraces at 95, llo. and 120 feet above the lake. They 
are probably related to a small stream which descends there 
through a ravine, but they undoubtedly mark the level of the 
lake at that time. Looking eastward from the roof of the 
smelter, the southward face of the mountain shows a distinct 
notch which looks very much like a sea-clitf. Captain Plum 
ami part of the crew of the •'Parnielee" made the ascent of 
the mountain and ascertained by barometric measurement
