MOUND No. 33 



This mound, like No. 27, was a great crematory altar. It was 

 30 feet in diameter and had an elevation above mean lake level 

 of 23.18 feet, or 3.6 feet above the surrounding land. Its stratifica- 

 tion was as follows : 



Surface loam 23.18 



Fire remains 20.98 



Light yellow sand 18.88 



Very fine light yellow sand 17.98 



Mottled sandy clay 14.78 



Golden streaked sand 14.58 



Bottom of Mound : 

 Gray clay 14.08 



These strata were in some places quite uneven. For instance, 

 at one point in a horizontal distance of 4 feet the loam ran from 

 2.2 to 3.7 feet in thickness. 



The fire remains measured 25 feet east and west by 17.5 feet 

 north and south. Their depth varied, attaining a maximum of 4 

 feet. This mound was also a depository for perishable offerings, 

 as was evidenced by the many streaks of decayed organic matter 

 found in the ceremonial strata beneath the great fire. The amount 

 of these offerings must have been considerable, since a large number 

 of unburned sacrifices, such as clothing, would have been necessary 

 to form these extensive lines which ran throughout the entire 

 extent of these strata. 



The depth of the ceremonial strata was 9.1 feet below the sum- 

 mit of the mound. They went down to the gray clay subsoil or 

 5.5 feet below the surrounding level showing that the erection of 

 this mound was no slight undertaking. Fig. 14 shows a plan and
