PEWKES] CASA GRANDE- MOUNDS 105 
character as the others, containing a massive building centrally 
placed, the walls of which have been greatly eroded by the elements. 
Within the surrounding wall were also numerous rooms whose 
fragile walls have fallen, burying their floors two or three feet. below 
the surface. At the periphery of one of the floors a row of holes in 
which upright posts formerly stood could readily be traced, show- 
ing that the room was rectangular in form and had a doorway on 
one side. The fireplace, a round depression in the floor just in 
front of the doorway, still contained ashes. The conditions here are 
similar to those in 
Compound B. The 
massive-walled 
buildings doubtless 
served as granaries 
or possibly were 
devoted to religious 
purposes; the frag- 
ile-walled struc- 
tures were the 
dwellings of the 
people. The eroded 
appearance of this 
compound suggests 
great age, stamping 
it as one of the 
oldest of the Casa 
Grande Group. 
In the character 
of the masonry the 
massive-walled 
buildings of Com- 
pound D_ closely 
resemble those else- 
where described. 
They are not as 
high as the corre- 
sponding structures 
of Compounds A and B, having been greatly weathered. The sur- 
rounding wall was low, in no place above the surface of the ground, 
and its course could not be traced by excavation. The Geel 
building was apparently connected by a wall with one side of the 
wall of ke compound. 
On the plastering of one of these buildings are black impressions 
of human hands (fig. 16). The rooms were excavated to their floors, 
but no objects of importance were found.
