Geographic Distribution
A list of the glacial lakes of North America is given in Table 7.12. The general locations of the
larger lakes are within the area identified as G2 in
Figure 7.1.
The significance of the charac-
teristics of lake bed soils lies in the fact that many of the larger cities of the United States are
located over former lake beds, including Chicago, Cleveland, Toledo, Detroit, Albany, and
parts of New York City. Boston is located over glacial-marine soils (see
Section 7.6.5).
