Abstract: 'This report primarily summarizes data from archaeological excavations at the Modoc Rock Shelter in 1987. This expedition is part of a long-term research project which focuses on prehistoric environmental change and cultural adaptation along the southern border of the Prairie Peninsula. The 1987 excavations explored strata previously radiocarbon dated to the early portion of the Late Archaic period (4000-5000 B.P.). Prior to 1987, these strata had been documented, but very little material had been recovered from reliable contexts.' (page 1). Ahler describes the previous research at Modoc Rock Shelter. He presents the results of the 1987 excavations and the lithic analysis. His analysis includes comparison of Strata 7E, 8E, 8EC, 9E, and 10E. The fauna, flora, skeletal, and additional analyses and the site summary can be found in eHRAF documents nos. 3-7.
