88 YEARBOOK, PUBLIC MUSEUM, MILWAUKEE [Vol. III. 



about fifteen feet above the original floor level of room 13, are the 

 remains of the walls of a room about eighteen feet in length. 



Rooms 15, 16 and 17. At a point about seventy-five feet north of 

 room 14, are three small storage rooms. 



Room 15 is but the vestige of a tiny storage room about three feet 

 long and a foot in height, extending back into the crevice a foot and 

 a half. 



Room 16. In a recess in the rock, about three and a half feet in 

 height, is this small storage room, three and a half feet in width and 

 extending back about four feet into the recess. Here were found evi- 

 dences of much fire, both in the form of ashes and charcoal and in the 

 smoke-blackened walls and ceilings of this niche. Just why this should 

 have been chosen as a fireplace, is, of course, not clear, especially in 

 view of the fact that the floor of this small room is about four and a 

 half feet above the present talus slope at the base of the cliff. Fur- 

 thermore, it has no outlet, which would serve as a chimney. 



Room 17. This is another small room in a recess of rock, at a 

 point about three feet above the talus slope. It is about three feet 

 deep and extends along this surface for about fifteen feet and has an 

 average height of about three and a half feet. The center of this room 

 shows much fire remains, all of which have been badly disturbed. In 

 these ruins were found a metati, with a deep depression worn on each 

 of its faces, several rubbing stones, broken pottery and many corncobs 

 blackened from age. 



At a point perhaps 200 feet up in the face of the cliff to the east of 

 Upper Ribbon Falls and perhaps an eighth of a mile from them, are 

 two tiny cliff ruins, one comprising two small rooms and the other 

 only one room. These are located about fifty feet apart and the one 

 room structure is perhaps twenty-five feet higher in the cliff than the 

 other. Both are extremely difficult of access. In the two room ruin 

 were found two well preserved metates and a fire drill base which 

 showed much use. 



Down in the middle of the small valley, between Upper and Lower 

 Ribbon Falls, is an old field, well cleared of cobblestones and present- 

 ing all the appearance of an ancient Indian corn field or garden. In 

 fact this little valley was ideally located for ancient habitation, being 

 naturally protected in almost every direction. 



WALL CREEK RUINS 



At a point about three-quarters of a mile up Bright Angel creek 

 from Altar Falls, is a very small stream known as Wall creek, entering
