SECRETARY’S REPORT “4 
Crow Straight Rim pottery predominates. The fourth component, 
occurring in area A, is represented by a house with an indistinct 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 (89BF221) 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 site (89ST30) near Pierre, S.Dak. At site 839BF220, 
situated about 1 mile west of the Akichita site, much of the occupa- 
tion area has been washed into the river. Two excavation units, each 
30 feet by 50 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 (89BF 224), 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- 
fact material recovered from the site suggests Woodland affiliation, 
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-
