Southwest. The reservation (fig. 2) includes four groups of ruins, 

 now called Ruin Canyon, Keeley, Hackberry, and Cajon. 



There are 13 ruins in the Ruin Canyon group, over half of which 

 are towers of the second type, which have kivas at their bases. One 

 of the largest ruins is in Square Tower Canyon and stands at the 

 head of the canyon, rising from the very rim. Although sections 

 of the walls of this building have fallen, the remains of a large semi-

circular house are conspicuous for some distance. This ruin also 

 has buried kivas surrounded by square or rectangular rooms. In 

 the midst of walls there formerly rose a conspicuous multichambered 

 tower, whose foundation is D-shaped, its straight wall measuring 23 

 and the curved 56 feet. The northeast corner rises 15 feet high, and 

 the walls of the northwest angle of the ruin are still higher. This 

 ruin, called Hovenweep House, resembles somewhat Far View House 

 on the Mesa Verde National Park.
