A sedimentary and petrographic study of certain glacial drifts
Capel Glacial Drift Hill Prairie Natural Area is located on a southwest-facing slope overlooking Lake Shelbyville in Wolf Creek State Park, 4 km east of Findley, Shelby County, Illinois (SW1/4, NE1/4, Section 7, T12N, R5E).
The soil of the glacial drift hill prairie is Miami loam, a highly eroded soil with little of the original A horizon present, the original loess deposits having eroded away (Gotsch 1996).
Glaciers deposited materials in many ways, so there are several kinds of glacial drift
. During the melting process, some debris simply dropped in place to form deposits called glacial till.
The study area includes the part of Indiana covered with glacial drift of Wisconsinan age--approximately the northern two-thirds of the State.

They are relatively shallow inclusions in the glacial drift
, and they vary in maximum depth from less than a meter to over 45 m (see Coburn et al.
trichocalyx occurs in three localities in the state, all of them on glacial drift prairies in Macoupin County (McClain et al.
Illinois contains many prairie inclusions, but glacial drift prairies are not common throughout the state (McClain et al.

The vascular flora of the glacial drift hill prairie at Windfall Prairie Nature Preserve, Vermilion County, Illinois, was studied during the 2005 and 2006 growing seasons.
