the surface of the mound. Due to cultivation and erosion, no as- 

 sociated post molds or other traces of the structure remain. Only 

 the line of stone used to chink the horizontal logs which held the 

 vertical posts of the structure in place was left. Such lines of stone 

 were found on the north side of the mound, some 150 feet distant, 

 and are likewise believed to be definite evidence of structures in the 

 upper portion of the mound. 



About 4 feet south of the north wall of Structure No. 1 was a 

 trench about 8 inches wide and 20 feet long. A single row of post 

 molds appeared in this trench. The molds could be traced only with 

 great difficulty along its entire length because of the softness and 

 the color of the loam in the trench. Plate 21, &, shows at the left 

 the molds in the trench. The loam-filled trench across the north 

 end of Structure No. 1 certainly represents a line of post molds at 

 least 18 inches or more above the floor of Structure No. 1. This 

 would have brought the bases of these posts to the same level as the 

 row of large rocks which crosses the south end of Structure No. 1 at 

 a level of about 18 inches above the structure floor. This row of 

 large rocks is designated as Feature No. 1. It is believed that this 

 loam-filled trench and Feature No. 1 together are parts of the same 

 structure built on this mound after the collapse of Structure No. 1, 

 with a floor level about 18 inches above the primary floor of 

 Structure No. 1. 



Approximately in the center of Structure No. 1 was a large fire- 

 place, Feature No. 15, a close-up of which is shown in plate 21, c. 

 This circular fireplace, made of hard-burned clay, is 3.5 feet in 

 diameter. It was raised 6 inches above the floor of the structure 

 in which it was used. The central pit was 18 inches in diameter 

 and 8 inches deep. On the northeast side of this fireplace is a cleft 

 or a shelf in the outer rim. This was not made during excavation 

 and so may have been an intentional feature. This niche is 18 

 inches broad and extends inward 13 inches. A large stone was found 

 associated with this niche on the northeast side at the time of excava- 

 tion. It is possible that this stone was once seated on the shelf as a 

 part of the altar. After the removal of the fireplace a circular 

 pit was found under it. This pit was approximately 3 feet in 

 diameter and 2 feet deep, and contained potsherds and burned frag- 

 ments of animal bones mixed with ashes and charcoal. 



In the northeast corner of Structure No. 1 was another small fire- 

 place which was designated Feature No. 17 on the plat. This fire- 

 place consisted of an area of hard-burned clay about 2.5 feet long 

 and 2 feet wide without the central pit. Along the side of this area 

 were two parallel trenches 3 inches deep.
