Book excerpt: This report describes the results of a Phase II Archaeological and geomorphological investigation conducted by Burns & McDonnell archaeologists and private consulting geomorphologist, Rolfe D. Mandel, Ph. D. The purpose of this investigation was to locate, record, and give a preliminary assessment of the National Register of Historic Places (NRHP) eligibility of all cultural properties identified within the proposed project area within the military facility at Fort Leavenworth, Kansas. The investigation involved archival, literature and records research of documents held at the Frontier Army Museum and State Historic Preservation Office (SHPO) at Topeka. During the investigation the records of all previously recorded sites, NRHP properties, and previous archaeological investigations within the fort were researched. Historic maps, photographs and engineering plans were studied to identify all historic structures within the project area. Archaeological fieldwork was limited to geomorphic studies using backhoe trenches within the project area. The goal of these studies was to remove the fill imported to the project area and examine the subsurface for intact cultural deposits, including both prehistoric and historic components. Attempts were made to examine the areas likely to contain historic features as revealed by archival research. Three "T" test trenches were excavated within the Area of Potential Effect. These trenches verified the presence of imported fill. On top of sterile loess fill up to 40 to 170 cm of modern fill, what is believed to be fire and other construction-related debris, had been deposited. No intact buried cultural material was found. The geomorphological investigations revealed that the likelihood of intact cultural deposits below the fill was virtually non-existent due to the presence of bedrock and a high water table.
