surrounding the East Mound. Here a rock wall originally 206 feet 

 long but now much disintegrated, screened the north side. At 80 feet 

 from its west end a flight of eight stone steps led up and over 

 (pi. 76, upper). The lowermost step, outside the barrier and without 

 foundation, measured 28 inches wide with a 24-inch tread; the 

 upper steps averaged about 15 inches wide and were protected from 

 encroaching debris by casually placed end-stones. At this stairway 

 the enclosing wall is double: an outer one of third-type masonry 

 18 inches thick and now 33 inches high built against second-type 

 masonry 24 inches thick. 



A second series of eight stone steps crosses the same wall 85 feet 

 farther east (pi. 76, lower). In this case the retaining wall, 37 inches 

 high on the east side of the steps and 28 inches on the west side, 

 clearly had been breached to allow for the crossing. The upper steps 

 average 25 inches wide and, like those of the first flight, rest directly 

 upon mound refuse and are screened at the ends by dry-laid stones. 

 The bottom step, 43 inches wide with a 22-inch tread, lies outside 

 the wall and upon 4 inches of blown sand that covers a hard and 

 fairly uniform adobe surface. 



Excellent third-type masonry, built upon a 12-inch foundation and 

 still 5 feet high, stands at the northeast corner of the enclosure 

 (pi. 77, upper). The corner foundation, in turn, rests upon an adobe 

 surface apparently continuing from that below the second series of 

 steps, 35 feet to the west. However superior the stonework at the 

 corner, it deteriorates rapidly southward along the east side : First, 

 two to four carelessly laid upper courses; then carelessness to a 

 greater depth (pi. 78, left). Halfway along its length the wall takes 

 a 5-foot outward jog, then south again to a low barrier, an appar- 

 ent improvisation, that extends east about 30 feet and there is 

 reduced to two uncertain courses. The opposite end of this exten- 

 sion is lost under the earth dam of Wetherill's reservoir, but 

 farther west a few salvaged sandstone blocks again provide a rude 

 barrier (pi. 78, right). 



The west end of this East Mound enclosure was originally con- 

 structed of second-type masonry. Subsequently a nondescript addi- 

 tion of three or more courses was piled on top. Still later, after the 

 middle section of this addition had collapsed outwardly, a new and 

 equally nondescript substitute was built 3 feet outside the original 

 (fig. 23). At the new northwest corner a rock-fenced area was pro- 

 vided for some unknown purpose, its adobe floor dipping unevenly 

 toward the west and the middle of it occupied by a crudely built 

 stone circle 45 inches in diameter (pi. 77 , lower).
