Landscape evolution and soil formation in southwestern Iowa
Kay (24), who originally defined gumbotil, reported the occurrence of gumbotil in
the section at Adair (25, p. 129). The horizons of the buried soil, IIBlgb to IIB3gb at
depths of 177 to 272 inches, are the gumbotil of Kay. Although the gumbotil ...

Geological Survey professional paper
At the type locality, as well as in other places in that general region, there is a
conspicuous development of gumbotil 10 at the top of the sub- Aftonian (
Nebraskan) till, which constitutes impressive evidence of prolonged interglacial
action.
Geological Survey (U.S.), Geological Survey (U.S.). Geographic Names Information Management, 1932
In some of the deep road cuts and along some of the major stream valleys, a
gumbotil can be seen below the Kansan glacial till. This is called Aftonian
gumbotil (5, 6). It consists mainly of glacial till made up of coarse fragments in a
clay loam ...

Gumbotil, a dark, sticky, clayey soil, averaging about 8 ft in thickness, has
resulted from the weathering of the till during the interglacial age. Scattered
deposits of peat have been found sandwiched between the Nebraskan and
Kansan tills.

Living Ice: Understanding Glaciers and Glaciation
The deeply weathered clay-rich zone, in places 3 meters thick, at the top of the
Nebraskan drift is appropriately termed gumbotil. Gumbotil is created by long-
continued weathering under warm, moist conditions, and a 3-meter thickness ...
