PREHISTORIC kENOSHA TOLD
Wonderful Story of the Formation OF
the Strata in Wisconsin and of the
Original Lake Line Changes Told to
Kenosha Club Members Wednesday.

A story of compelling interest Of
Prehistoric Wisconsin and Prehistoric
Kenosha County was told TO the mem
bers of the Woman s Club of Kenosha
on Wednesday afternoon when Mrs.
Mary d. Bradford gave 20 the members
of the club the results of long years
of research along geological lines.
The address was on the subject Gee
illogical History Wisconsin With Es-
pecial Emphasis on Traces of Glacial
History in Kenosha County"
In her carefully prepared talk, Mrs,
Bradford outlined the prehistric lines
of Lake Michigan, she showed the de-
velopment of Wisconsin as a part of
the world starting with the develop
ment of the little island from the pri-
meval ocean near Stevens Point. 1t
was not technical discussion of geolo-
gy, but an interesting story of just
how KenOsha county. had been de-
veloped. She traced the formation of
the rock layers from the lowest, the
postdam sandstone, to the Niagara
limestone, the rock layer now nearest
the surface. 1t was story of de-
velopment of sixty million years ago.
Mrs. Bradford held in her address that
Wisconsin first came from the prime
val ocean this long time ago when a
tiny island was made near the present
site of Stevens Point and that in the
years which multiplied the island grew
larger and larger until finally it came
to be the great state of Wisconsin and
tht built about this tiny island were
the other states of the union.
She declared that in the prehistoric
days the west shore of Lake Michigan
extended as far west as the ridge on
which the Chicago and Milwaukee
wagon road is now located and that
year after year TIE beach of the lake
receded until finally it reached its
present confines. She told of the com
ing Of the great glaciers which dipped
one foot in Lake Superior and the
other in Lake Michigan and passing
over the face of the country all the
way from Northern Michigan to the
shores of the Ohio river this great
glacier sc0oped out the lakes and form
ed the rivers. She spoke especially Of
this glacial development in Kenosha
county which made possible the beauti-
full lake regions in the western part
of the county. She spoke OF tahe com
ing of Washington Island and Jacobs
Island as a result of the recedinp of
the waters of the lake.
She discussed at length the rock de.
velopments of Wisconsin and the
"drift' which had been placed over
them in the course of the glaciers and
showed that this drift in Kenosba
county was between four and five
hundred feet in depth She showed the
development of streams of water in
this drift and how these streams had
furnished water supply for wells.
Touching the geological development
OF the state she spoke of the glacial
and volcanic action which had brought
the great deposits of lead and zinc and
copper in various parts of the state
and in the Michigan peninsula. She
spoke of the one great district in the
state which was outside of the drift
area and declared that this was prob
ably the only district of the kind in
the world. Much of the matter shown
by Mrs. Bradford was sustained bv
ancient maps which were shown to the
club women in connection with fine
interesting address.
