Ruin 6
This ruin is a small tower whose curved walls are so broken down that the form is not evident. It is situated in the base of the talus at the head of the South Fork ([pl. 26, a]).
Eroded Bowlder House
(Ruin 7)
This house, more remarkable from its site than its structure, was constructed in an eroded cave of a bowlder halfway down the talus of the cliff. The front walls are somewhat broken down, but others built in the rear of the cave still remain intact. On the top of the bowlder is the débris of fallen walls, suggesting a former tower, but not much remains in place to determine its outlines. Where the walls are protected the mortar shows impressions of human hands and at one place there are the indentations of a corncob used by the plasterers to press the mortar between the layers of stone. There were formerly at least two rooms in the rear of the cave, the front walls of which have fallen and are strewn down the talus to the bottom of the canyon.
Twin Towers
(Ruin 8)
The so-called Twin Towers, which seen together from certain points appear as one ruin ([pl. 15, a], [b]), rank among the most impressive buildings in Square Tower Canyon. They stand on the south side of the canyon on a rock isolated by a cleft from the adjoining cliff. The larger ([fig. 9, A-E]) has an oval ground plan and a doorway in the southwest corner; the smaller (F, G, H, I) is horseshoe shaped with a doorway in the east wall, which is straight. The arrangement of rooms is seen in [figure 9]. Small walled-up caves are found below the foundation on the northwest base of the larger room.

Ruin 9
The ground plan of this ruin is rectangular in form, 19 feet 6 inches long by 10 feet wide. The standing walls measure 11 feet in altitude. It is situated on the south rim at the mouth of the South Fork, just above Ruin 7, a few feet back from the cliff. A doorway opening in the middle of its north wall was formerly made difficult of entrance by walls, now fallen, extending from the northeast and northwest angles to the edge of the cliff. The masonry throughout is rough; projecting ends of rafters indicate a building two stories high. There are peepholes with plastered surfaces through the southeast and west walls, which suggest ports. A short distance east of the building is a circle of stones reminding the author of a shrine.
