ported sequence for the Santa Barbara area. It also indicated that 

 two phases each of the last two periods might be defined as the result 

 of further work. The same party also did some testing in another 

 site which apparently represents a single late period that extended 

 into early historic times. 



The party under Mr. Baumhoff concentrated its efforts at the second 

 site where Mr. Mohr worked and obtained considerable additional 

 information from it. Preliminary study of the artifacts indicates 

 that the occupation is attributable to the Canalino. There is evidence 

 of trading activities in the form of tubular beads from the San Joaquin 

 Valley and potsherds similar to the pottery made by the Yokuts of 

 that region and the western Paiutes. No house remains were found, 

 but there were scattered piles of stones that appear to have been inten- 

 tional rather than accidental, and in one case there was a pear-shaped 

 pit 12 feet 8 inches long, 6 feet 3 inches wide, and 1 foot 3 inches in 

 depth, which had been lined with slabs of shale and was filled with 

 rocks of all sizes. The function of the pit has not been determined. 

 It was at first thought that the feature may have been a sweat house, 

 but the nature of the shale lining was such that it probably would 

 not have withstood the heating necessary for sweat-house purposes. 

 Additional work is needed at the Cachuma Reservoir in order to gain 

 a better understanding of the aboriginal history of the area. 



Columbia Basin. — ^Work in the Columbia Basin was continued under 

 the supervision of the field headquarters at Eugene, Oreg., where 

 laboratory and office space were provided by the University of Oregon. 

 Joel L. Shiner served as acting field director throughout the year. 

 Activities in that area consisted of a survey of six reservoir projects 

 and excavations in four areas where preliminary reconnaissance work 

 had already been completed. The John Day Reservoir basin on the 

 John Day River, in Oregon,' was examined by Robert Farrell and 

 Stuart Peck during the first two weeks in July. The party found 88 

 sites and recommended testing or more extended excavations for 8 of 

 them. From the John Day Reservoir, Peck and Farrell proceeded 

 to the Hells Canyon Reservoir on the Snake River, in Oregon-Idaho, 

 where they found 22 sites, of which 4 were recommended for investiga- 

 tion. The latter survey was completed the middle of August. During 

 July George L. Coale and Octavio Romano surveyed the area to be 

 flooded by the Albeni Falls Reservoir on the Pend Oreille River, in 

 northern Idaho. They found 13 sites and recommended the testing of 

 5. Construction work on the dam has progressed to such an extent 

 that the indicated work may not be possible at that location. From 

 the Albeni Falls area, Coale and Romano proceeded to the Katka 

 and Libby Reservoir projects on the Kootenai River, in Idaho and 

 Montana, where they made a preliminary reconnaissance. The Katka 

 Dam is located in Idaho, but the reservoir will extend upstream into
