association. A post mold 36 inches in depth and 18 inches in diam- 

 eter was found beneath the rock near the center of the feature. 



Feature No. 5. — This feature was a pattern of post molds 6 feet 4 

 inches by 6 feet, which appeared at a depth of 6.2 feet in the hard- 

 pan, as shown in plate 99, a. Associated with the mold system wer9 

 a burned area, an ash pit, and a nut stone. 



Feature No. 6. — This feature was a burned structure on the clay 

 floor of the mound. This structure lay on the hardpan floor, except 

 the northwest corner, which was some 6 inches below the surface of 

 the hardpan. This structure had been covered over by burned clay 

 and burned thatching. The clay lay above the thatching. 



In the northeast corner of the structure there was a pile of small, 

 irregularly placed stones in which were mixed potsherds, shell, and 

 burned thatching. The post molds here indicated that the walls of 

 this small structure contained posts about 2% inches in diameter. The 

 smallness of this structure, the evidence of fire, and the further fact 

 that this small structure had a clay covering over the thatch (sup- 

 ported by poles) strongly suggests the possibility that this was a 

 "sweat house", 1 the prehistoric approach to a Turkish bath. The 

 ground plan of this post-mold pattern and fire basin of stone are 

 shown in figure 64. 



Feature No. 7. — This was a rock pile found at a depth of 6 feet, 

 southeast of stake 6.3. This pile was about 3 feet in diameter and 

 had in association shell, animal bones, and potsherds. 



Feature No. 8. — Three large rocks were arranged in the same hori- 

 zontal plane, northwest of stake 8.0. They were at a depth of 2.5 

 feet, and seemed intentionally placed. Their purpose was not 

 ascertained. 



Feature No. 9. — This was a rock pile with shell and potsherds in 

 association. This pile was 24 by 42 inches, and was 2.5 feet below 

 the surface of the mound. 



Feature No. 10. — This was a hard-packed floor about 6 inches be- 

 low the surface of the mound. An accurate outline of this floor was 

 not determined because of its nearness to the surface and its partial 

 destruction by the plow. No post molds were found associated with 

 this floor, which was especially well defined in some areas. Feature 

 No. 1 was a fire pit on this floor. 



Feature No. 11. — This was a circular, baked fire pit, as shown in 

 plate 100. The pit was carefully constructed. It was on the floor 

 of the structure of this mound southwest of stake 4.0 and at a depth 

 of 3 feet 2 inches. The pit was accurately circular in form. It was 

 68 inches in diameter and 10 inches deep. The outer rim of this 

 basin rose 4 inches above the floor. It was filled with ashes and 

 charcoal when found.
