SEVENTY-SIXTH ANNUAL REPORT 23 



Crow Straight Kim pottery predominates. The fourth component, 

 occurring in area A, is represented by a house with an mdistinct post 

 pattern buried in Stanley and Fort Thompson refuse. The associated 

 ceramics are varied, and at this time no definite assessment can be 

 made of them. 



The investigations in areas A and C at the Medicine Crow site 

 represent the first clear-cut Stanley occupation excavated south of 

 the Oahe Reservoir. It is also important to note that a temporal re- 

 lationship can now be established between the components involved. 

 European trade materials found in association with Stanley features 

 may be helpful in providing absolute dates for the latest occupation. 

 The Deetz party terminated fieldwork on August 30 after 12 weeks 

 in the field. 



The third River Basin Surveys party in the Big Bend Reservoir was 

 comprised of a crew of 10 men, under the leadership of Robert W. 

 Neuman. This party excavated or tested a series of four sites in the 

 vicinity of Old Fort Thompson and three sites on the right bank of 

 the Missouri River, in and adjacent to Good Soldier and Counselor 

 Creeks. All seven sites are within the dam-construction area. The 

 initial effort was devoted to the Akichita site (39BF221) located in 

 the Missouri River bottoms adjacent to Old Fort Thompson. The 

 site had been tested during the 1957 season, but although extensive 

 evidence of occupation was recovered, no house structures were found. 

 A network of five extended test trenches, excavated during the 1958 

 season, was equally unsuccessful in locating habitations. Cache pits 

 were the only structures uncovered. The artifact collection is exten- 

 sive, and shows clear relationship to the Anderson-Monroe material 

 from the Dodd sit^ (39ST30) near Pierre, S.Dak. At site 39BF220, 

 situated about 1 mile west of the Akichita site, much of the occupa- 

 tion area has been washed into the river. Two excavation imits, each 

 30 feet by 60 feet, produced only a limited artifact return. However, 

 a number of pottery types were recovered. The inventory suggests 

 that the site was occupied by circular-house people. 



The Truman Mound site (39BF224) , also in the Old Fort Thompson 

 area, on the first terrace overlooking the river, was revisited for a 

 second season in order to excavate the remaining two of the six mounds 

 originally present there. The mounds, 1 to 2 feet in height, 50 feet 

 in diameter, contained two types of burials : (1) secondary interments 

 in shallow circular pits, (2) primary burials in deep oval pits. Arti- 

 I fact material recovered from the site suggests Woodland afiiliation, 

 ! but the conical-shaped vessels excavated are clearly simple-stamped, 

 rather than the Woodland cord-marked type. In a stratum beneath, 

 and not associated with the mounds, excavations recovered a number 

 of stone artifacts. The most diagnostic type is represented by a tri-
