Blake Mound 23SL51

The Blake Mound archaeological site (23SL51) was discovered and reported to the Archaeological Survey of Missouri by Leonard Blake during the 1950s. His survey led to the site being placed on the National Register of Historic Places as part of an Archaeological District. Acting upon the recommendations of Joe Harl (Archaeological Research Center of St. Louis), the property owner agreed to form a protective covenant with the State of Missouri, promising never to build on, nor destroy the mound. The site IS NOT open to the public.

Ramey Incised rimsherd from feature no. 140 found in association with a mortuary house at the Blake Mound site by Joe Harl. Ramey Incised pottery associates with the Stirling Phase (AD 1100 to 1200) and Moorehead Phase (AD 1200 to 1275) at Cahokia Mounds in Illinois. Same as the sherd drawing published by Leach (2005:Figure 7). This specimen was discovered during 1994 as a result the rescue excavation by University of Missouri at St. Louis of the village at the foot of Blake Mound.



Cordmarked, shell tempered sherd with neck smoothing that Joe Harl classified as Emergent Mississippian (approximately A.D. 800-850) at 23SL51. This specimen was discovered during 1994 as a result of the rescue excavation by University of Missouri at St. Louis of the village at the foot of Blake Mound.



Outline and floor of a mortuary house (structure number 7) at the Blake Mound site; excavation and photograph by Joe Harl. The numerous pieces of limestone on the northern half of the floor are interpreted by Harl as pedestals where human bodies were placed or altars where food offerings or figurines were placed (Leach 2005:18).

The first step of the restoration was to document the pre-restoration condition of the mound.



Kathleen Stahlman of PARC (Powell Archaeological Research Center) and Robin Machiran (lecturer in Archaeology at the University of Missouri - St. Louis) used a combination of GPS and Total Station equipment to map the mound.
