were trenched and the third was half excavated. Central hearths 
were found in all cases. Three additional tests were made on the 
site. Artifact recovery was fair, but architectural data were poorly 
represented, owing to the shallow depth of fill above house floors 
and the clayey nature of the soil. The houses were probably circular 
and the pottery in the La Roche tradition. 
The Zimmerman site (89SL41), located on the same terrace as the 
Nolz site, consisted of a village area marked by about 40 large round- 
to-oval depressions. One rectangular house was excavated com- 
pletely, and half the fill of a second was removed. A midden area and 
12 cache pits were also excavated. There was no indication of the 
presence of any other component. Three exploratory trenches were 
dug, in an effort to find a fortification ditch, but no satisfactory ditch 
profile was discovered. The total data indicate that this was a single- 
component site, characterized by long-rectangular houses and Thomas 
Riggs pottery. 
The Glasshoff site (895142) was situated on the Zimmerman-Nolz 
terrace below the west end of the Sully site. According to an in- 
formant, the area was once used for cavalry exercises by Fort Sully 
personnel. In the past, sherds were collected from the surface there, 
and one test excavation (1953) had provided additional evidence 
of aboriginal occupation. No well-defined house depressions were 
apparent, but several surface anomalies were visible. Wherever tested, 
they proved to be the result of activities attributable to the occupa- 
tion of Fort Sully in the late 19th century. Trenching during the 
1958 season yielded historic specimens, a cache pit, and a part of an 
aboriginal dwelling. The latter was found on the last day of the 
field season. Artifact recovery was fair, and although some archi- 
tectural features were well preserved, few details were discernible. 
Pottery is simple-stamped and somewhat like the Thomas Riggs 
materials, but it appears to be a distinctive variant. 
Site 39SL27, a large, unnamed site on Telegraph Flat, 1 mile east 
of the Sully site, has several visible but shallow “house” depressions. 
Three small pits dug in the centers of depressions yielded neither 
artifacts nor architectural features. Additional work is needed at 
this site. 
The Whistling Hawk site (89SL39) comprised a large area along 
the edge of Telegraph Flat terrace, east of 39SL27. A single pit 
excavated into a deep (house?) depression yielded no artifacts or 
architecture, although the Bass party excavated rock-cairn burials 
at the site. 
Two sites not situated in Fielder Bottom were also tested. Site 
39SL19 was a low-lying area in the Little Bend region, 18 miles 
upstream from the Sully site. Two small, shallow pits were dug to
