There does not appear to have been a doorway on the south side, and 

 there is not space for rooms on this side on account of the nearness 

 to the edge of the cliff. While the form (fig. 13) of Horseshoe Ruin re- 

 calls that of Sun Temple, in details of room structure it is widely 

 divergent. The length of the south wall, or that connecting the two 

 ends of the horseshoe, is 30 feet, its width 27 feet; the highest wall on 

 the northwest side is 12 feet. Figure 13 shows the arrangement of 

 the rooms and the mutilation of the south wall of the ruin. The dis- 

 tance between the outer and inner concentric walls averages 4 feet; 

 the circular room is 17 feet in diameter. 



In the same cluster as Horseshoe Rum (pi. 24, a) there is another 

 well-made tower (fig. 12,4), constructed on a point at the entrance to 

 the canyon, and below it in a cave are well-preserved walls of a cliff- 

 dwelling.

Fig. 13.— Ground plan of Horseshoe House. 



A short distance due north of Horseshoe House, at the head of 

 a small canyon, a tributary of Bridge Canyon, there are two large 

 pueblos and a round tower. The pueblos are mentioned by Prudden, 

 who gives a ground plan which indicates an extensive settlement. 



TOWERS IN THE MAIN YELLOW JACKET CANYON 



Of the several towers and great houses of the main Yellow Jacket 

 Canyon two may suffice to show their resemblance to those in Square 

 Tower Canyon. The two towers considered belong to the D -shaped 

 variety, the straight wall, as is almost always the case, being on the 

 south side.
