72 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1948 
reference by the staff in correlating archeological materials with those 
of known tribes. The Thwaites and Biddle editions of the Lewis and 
Clark journals and the Ordway journal were the sources examined 
for the desired information. A total of approximately 1,500 items 
pertaining to tribal locations, contacts, material culture, and other 
features were extracted from these journals. When this material has 
been prepared for filing under tribal and subject-matter headings, it 
probably will fill some 15,000 index cards. 
From April 4 to June 26 Mr. Bauxar was on special assignment to 
the National Park Service for the purpose of conducting historical 
investigations at the Homestead National Monument in Gage County, 
Nebr. Five limited areas were examined, and a report on the excava- 
tions was prepared and submitted to the National Park Service, 
Region Two Office, at Omaha. Upon the completion of this detail 
Mr. Bauxar returned to the Lincoln headquarters and resumed his 
work on the ethnohistory project. 
On July 1 Wesley L. Bliss, archeologist, was working with the 
field party under his direction at the Glendo Reservoir project in 
Platte County, Wyo. The survey of this area, started in the month of 
June, was completed on July 2, and having located a total of 43 sites 
the party moved the following day to Boysen Reservoir, in Fremont 
County, where further investigations were carried on until July 26. 
During this period tests were made in Birdshead Cave in the Owl 
Creek Mountains about 5 miles west of the dam site. This cave 
showed six levels of occupation, and prospects for obtaining interest- 
ing information about the aboriginal inhabitants of the area were so 
promising that plans were made to return to it later in the season. 
On July 27 the party moved to the Oregon Basin project in Park 
County where it continued reconnaissance work, locating additional 
sites which increased the total for the basin to 28, and did some test 
digging in two rock shelters. August 11 it moved to the Canyon 
Ferry Reservoir near Helena, Mont. Investigations there added to 
the number of sites located during the preliminary examination of 
the area in 1946, making a total of 31. The work there was completed 
on August 26, and attention was turned to the proposed Tiber Reser- 
voir near Shelby, Mont., where work continued until September 9. 
During this period Mr. Bliss and his party spent 4 days traveling by 
boat in order to locate and examine sites exposed along the river-cut 
terraces. These sites could not be reached by land and were not 
visited during the preliminary reconnaissance made the previous year. 
Additional sites located bring the total for Tiber to 53. Leaving this 
area, Mr. Bliss returned to the Boysen Reservoir and from September 
11 to November 6 completed excavation of the Birdshead Cave and 
did some test digging in other sites. He returned to Lincoln on No- 
vember 8 and from then until the end of the fiscal year was engaged
