The walls are double, the interval between the inner wall and that of 

 the circular chamber being rilled in with solid masonry. 1 The outer 

 of the two enclosing rectangular walls is separated from the inner 

 by an interval of about 7 feet, and is connected with it by thin parti-

 concentric walls 2 of circular towers on the McElmo.

2 The circular kivas of the two ruins near Crown Point are enclosed by four 

 standing walls forming sides of a rectangle, a feature they share with some of 

 these chambers in the Chaco and San Juan region. The intention of the

 a rectangular building about the circular room rather than by depression below 

 the level of the site. This type is now extinct, but belongs to the most advanced 

 stage of pueblo architecture before its decline.
