Summary

This project includes data from the 1987 excavation season at Modoc Rock Shelter (11R5). The 1987 archaeological excavation was directed by Dr. Steven Ahler under the auspices of the Illinois State Museum. Funding was provided by grants from the National Geographic Society (Grant No. 3621-87) and the National Endowment for the Humanities (Grant No. RO-21430) to the Illinois State Museum Society. Dr. Steven Ahler served as the Principal Investigator with Drs. Bonnie Styles and Melvin L. Fowler serving as Co-Principal Investigators. The Illinois State Museum and the MacLean-Fogg company provided supplemental funding.

The 1987 field season excavation focused on strata in the East Pillar area of the Main Shelter that radiocarbon dated to the early Late Archaic period. Four 1.5 m by 1.5 m units (Units K, L, M, and N) were excavated in no more than 10 cm levels following the natural and cultural stratigraphy. Sediments were dry-screened through 1/4" mesh. A standard flotation sample of 15 liters was taken from each level, and a 0.4 liter sample was taken for soil/sediment analysis. The flotation samples and sediment samples were taken roughly in a column, but were offset to avoid features or disturbances to the sediment matrix.

Faunal remains reported here were recovered by dry-screening through 1/4 inch mesh and from flotation (heavy fraction) using 1/16 inch mesh. Using the comparative faunal collection at the Illinois State Museum, Paula Thorson identified vertebrate remains from 1/4" screen and flotation and Dr. Bonnie Styles identified freshwater mussels from 1/4" screen only. Dr. Bonnie W. Styles directed the faunal analyses and verified faunal identifications.
