Charles Monson


I'm a PhD candidate working with Jim Best on basal Cambrian sandstones (Mt. Simon, "Argenta," Lamotte) in Illinois and Missouri. I was previously employed at the Illinois State Geological Survey working primarily on geological carbon storage projects and subsurface mapping. Apart from my PhD work, I am also engaged in ongoing research on the Glasford meteorite impact structure in Peoria County, Illinois.

Research Interests

*Paleozoic stratigraphy


*Meteorite impact craters

*Invertebrate paleontology

*History of geology
