NOTES ON THE ABANDONED BEACHES OF THE 
NORTH COAST OF LAKE SUPERIOR. 
By Frank B. Taylor, Fort Wayne, Indiana. 
[Plate V]. 
The month of September, 1895, was spent by the writer 
chiefly in searching for abandoned beaches on the north coast 
of lake Superior.* This const was studied by Prof. A. C. 
Lawson in the summer of 1892 with special reference to evi- 
dences of submergence, and his observations are recorded 
very fully in his report entitled "'Sketch of the Coastal Topog- 
raphy of the North Side of Lake Superior with Special Ref- 
erence to the Abandoned Strands of Lake Warren." f 
The high value of Prof. Lawson's observations was not 
questioned, but his methods of correlating the abandoned 
strands observed at different localities, and the general con- 
clusions which he based on this correlation have been review- 
ed and discussed in papers already published.;]; By reference 
to Prof. Lawson's report it will be seen that he tabulated his 
results at forty-eight localities between Duluth and Sault 
Ste. Marie in a substantially horizontal series. § He supposed 
the greatest interval between the varying bights of any single 
continuous strand to be about thirteen feet. || His conclusion 
in substance is that the abandoned strands of the north Supe- 
rior coast are almost as perfectly horizontal, when compared 
with the present lake surface, as they were when they were 
made, and therefore, that, altiiotigh tliis coast has been great- 
ly'uplifted relatively, it has not suifered ixny notable irregu- 
larit}' or deformation. That is to say, the region appeared to 
have been greatly uplifted, but so evenly over the whole area 
that the strands retained their horizontality after elevation. 
This was not the case on the south coast of lake Superior nor 
on aii}^ other coast of the upper lakes so far as known to the 
writer. It seemed to the writer that in his detailed description 
Prof. Lawson has not shown facts that could form an ade-
