The U.S. Geological Survey (USGS) in cooperation with the Little Rock District, U.S. Army Corps of Engineers conducted a bathymetric survey of the Black River from Clearwater Lake Dam near Piedmont, Missouri, to southern Butler County, Missouri, from June 16-19, 2020, and from June 22-24, 2020. One hundred and eight sites were surveyed at pre-established transect locations along a 45-mile reach at distances spaced from about 0.3 to 2 miles apart. River-channel cross sections were surveyed to determine water depths along each transect using an acoustic Doppler current profiler (ADCP). Positional location of the water-depth locations was obtained from a global positioning system receiver onboard the ADCP. Water-surface elevation at the water-depth locations was computed using vertical control points collected at the location of the cross sections with survey-grade Global Navigation Satellite Systems (GNSS) equipment. Standard methods of practice (Rydlund and Densmore, 2012) were use ...

In 2003, the GSA, Northeast and Caribbean Region, sought assistance from the U.S. Army Corps of Engineers, St. Louis District’s Mandatory Center of Expertise for the Curation and Management of Archaeological Collections (MCX) to assist with the archival processing of the associated records generated from investigations conducted at the New York African Burial Ground (ABG) in Manhattan, New York City. During the preliminary phases for the construction of a new building in 1991, archaeologists discovered a large historic cemetery used by African and African American slaves in the seventeenth and eighteenth centuries. This site is of both national and international significance and has been the subject of much debate and controversy. The project resulted in the recovery of over four hundred individual burials of human remains and associated burial artifacts as well as other material remains unassociated with the historic cemetery (i.e., stratigraphically located above the cemetery levels). The MCX began the transferring materials to St. Louis for archival processing in 2004. Record groups were transferred as their creators completed their research on the African Burial Ground. In all, 13 record groups were transferred to St. Louis between 2004 and 2009. When the archival processing of these materials was completed, the collection was delivered to the New York Public Library, Schomburg Center for Research in Black Culture, where the collection was legally transferred from GSA to the Schomburg Center on 30 September 2009.

Phase I and Phase II Archaeological Investigations of one historic site (38SU62) were performed at Shaw Air Force Base in Sumter County, South Carolina. The work was accomplished by New South Associates, Inc, subcontractor for Geo-Marine Inc., for the U.S. Army Corps of Engineers, Fort Worth District, and the U.S. Air Force, Shaw Air Force Base (AFB). Initially site 38SU62 was believed to represent an earlier occupation in the area. Artifacts recovered from surface collection during the previous work included decorated ceramics and olive green container glass, dating from the 1830s to the 1860s, as well as two prehistoric chert flakes. Artifacts recovered during Phase I/II testing and historical research indicate that site 38SU62 is an early twentieth-century historic scatter associated with a small farm owned and operated by Mathew Wiley. Historical documentation provides that Wiley is of African–American descent and owned the land between 1945 and 1974. Artifacts recovered from a small portion along the eastern boundary of the site are likely associated with an earlier occupation in the area. However, no intact midden was encountered in this area and an erosional gully passes through the area. It is likely that a majority of the nineteenth-century site was impacted by past construction of residential housing and the Wiley occupation. A large portion of the artifact assemblage is related to Wiley’s occupation. A possible posthole was recorded; however, no intact archaeological deposits or subsurface structures were encountered and evidence of mechanical ground disturbance was present. No prehistoric artifacts were encountered during initial subsurface testing and therefore, this component was not investigated during Phase II testing.

Although few sites related to African-American farm owners in the region have been studied, site 38SU62 lacks archaeological integrity and is recommended as not eligible for the National Register of Historical Places and no further work is needed.
