NO. 1873 PREHISTORIC RUINS IN GILA VALLEY FEWKES 

 3. SEVEN MILE RUIN 



431 



This ruin is situated 7 miles from Monmouth, on the left bank of 

 the river. One takes the road on the east side of the river to 

 Clark's ranch, then crosses it to the bluffs on the side. These bluffs 

 have been very much eroded since the site was inhabited and many 

 of the walls have been washed out, revealing many specimens of 

 minor antiquities. 



The surface of the ground is covered in places with fragments of 

 pottery. There are no high mounds, but the rooms are indicated 

 by the tops of their walls projecting out of the sand. These rooms 

 seem to have been arranged in blocks.

 4. RUIN NEAR CLARK'S RANCH 



This ruin is remarkable in having indications of circular rooms 

 that remind one of kivas or subterranean "pit dwellings." These 

 resemble reservoirs or wells, their true nature being as yet unknown. 



5. FIFTEEN MILE RUIN 



This ruin (fig. 74) is situated 15 miles up the river from Mon- 

 mouth, on the opposite side of the road from a small ranch house. 

 Not far from it there is a natural rock formation of red color that 

 might be mistaken for a house perched on top of a much-eroded mesa. 

 It is suggested that this building may have been at or near the site of 

 Kino's rancheria Arivaipa, which was not more than 27 miles from 

 the mouth of the Arivaipa Canyon.
