:?7s The American Geologist. Jane, 1894 
lines were observed until an altitude of about 450 feet was 
reached. At this level sand begins to overlie the elaj\ 
Maple Ridge. About a mile east of Poplar station, at about 
4b<> feet, there is a magnificent beach ridge and lagoon south 
of the railroad extending for a long distance. About a mile 
and a half east of Maple Ridge station, the upper limit of 
submergence was found very clearly developed as a beach 
ridge with a depression behind it. Its altitude is about 535 
feet above lake Superior, which is the same as Prof. Lawson's 
highest at Duluth. The railroad crosses the beach and for a 
mile or two passes over ground above its level. Then it de- 
scends again and crosses the beach on the eastern slope west 
of Blueberry station. Immense deposits of fine gravel and 
sand were crossed near the Bois Brule river and two or three 
other streams. 
Iron Hirer. At Iron River the ground was examined with 
some care, but the results were not decisive. The immense, 
rolling gravel deposits south of the town are so unlike ordi- 
nary littoral features that it seems certain that they are of 
glacial origin. Still, they are much like certain postglacial 
deltas which I have seen at several other places. About a mile 
north of the town and at an altitude of about 510 feet above 
the lake there is a well formed beach ridge of gravel. On the 
front of the sand hill south of the town there is a faint terrace 
at about 555 feet, which may be a shore line, but this is not 
certain. This place was left with the impression that the 
highest beach had not been certainly identified. 
Kimball. At Saxon the country is so new and there are so 
few roads that I was unable in the time at my disposal to 
reach the probable level of the highest beach. No distinct 
beaches or terraces were seen at this place except some grav- 
elly stream-terraces on Mr. Emory's farm in the valley of the 
east branch of Potato creek, about two miles southwest of tin- 
station. Their age was not determined. But in going by 
rail from Saxon eastward the highest shore line was crossed, 
about two miles west of Kimball. Its highest level here is a 
cut terrace and is well defined. Within a short distance, at 
slightly lower levels, beach ridges were also seen. The alti- 
tude of the highest beach at this place is about 570 feet above 
the lake.
