Fig_0870_Photos_001. Photo of the sandy facies of the Hagarstown Member of the Pearl Formation. This photo was taken in 2006 at the Keyesport Sand and Gravel Pit in Clinton County, Illinois. More information on the stratigraphy and geologic history is provided in the FOP Guidebook of Grimley and Phillips (2015). The Sangamon Geosol solum (reddish brown) is developed into the upper couple meters of the unit in the photo. High-angle reverse faulting is interpreted to be from ice-block melting. The depositional environment is here interpreted to be an ice-walled channel. Photograph by David Grimley, May 2006. +
Fig_0870_Photos_002. The Munie Pit in Madison County, Illinois. Pictured are David Grimley (ISGS) left and Gerry Berning (USDA-NRCS, Soil Scientist) on the right, for scale. Sangamon Geosol development is visible in the upper portion of the unit. This area contains fine sand beds, as well as areas with diamicton beds in the upper portion. It was therefore mapped as the mixed facies in some parts of the pit. Photograph by Andrew Philips, 2004. +
