alluvium over stratified outwash and has a black A horizon
to 6 in. (15 cm) that overlies a thin grayish brown E horizon
and grayish brown Bg (gleyed) horizons.
The most common Eutrudepts are the Minoa, Greysolon,
Mesaba, Barto, Detour, Rockland, Summerville, Ensign, and
Normanna soil series. They are especially prominent along
the northwest shore of Lake Superior. The Barto and Mesaba
soil series (Eutrudepts) are shown in Fig. 5.13. The Barto
soil series (Fig. 5.13a) is a Lithic Eutrudepts and originates
from 33 cm of loamy till over unweathered bedrock and has
a black A horizon over a brown Bw (cambic) horizon. The
Mesaba soil series (Fig. 5.13b) is a Dystric Eutrudepts and
also has developed from loamy till over bedrock. The
horizonation is similar to that of the Barto except that the
cambic horizon is thicker, i.e., extends to 29 in. (74 cm).
The Lenawee, Parkhill, Painesville, and Conneaut soil
series are the most frequently occurring Epiaquepts in the
GLCZ. The Nevens soil series is a Typic Epiaquepts
(Fig. 5.14). The Nevens soil series is derived from loamy
material overlying dense till. The profile is composed of a
very dark brown A horizon to 6 in., followed by a cambic
horizon (Bw) to 37 in. (94 cm).
The Ira, Sodus, and Williamson soil series are common
Fragiudepts and occur primarily along the southeast shore of
Lake Ontario. The Chenango soil series is a Dystrudepts that
is common on Lake Erie. The Tatches soil series, a Lamellic
Dystrudepts, occurs along Lake Michigan (Fig. 5.15). The
Tatches soil series is derived from loamy over sandy outwash and has a thin very dark gray A horizon over strong
brown Bw horizon to a depth of 32 in. (81 cm). The lamellae
