In 1919, Kidder and Guernsey could only begin to guess at the relative ages of the Cliff-dwelling and Basket Maker cultures that left the artifacts they excavated ([Kidder 1919], pages 209–211).
Guernsey excavated four reed flutes, each with a single finger hole.
The likely Early Woodland item is only the second documented cane flute in the Eastern Woodlands, the other deriving from a rockshelter in the Ozarks (Carstens and Di Blasi 2004).
Pictographs were documented nearby on a breakdown boulder in the Devil's Looking Glass area of Upper Mammoth Cave.
They were located in Cave 1 on the South side of Kin-Boko Canyon (also called “Kinboko” and “Kin Boo Koo”), on the Western side of Marsh Pass, South West of Kayenta in North Eastern Arizona.
The flutes were designated items 31 to 34 and described in [Kidder 1919], page 186: These range in length from 4 inches to 4¾ inches.
Dimensions are given as “10.9, 22.7, 6.9, 5.9 cm (fragments)”, but it is not clear which flute is which, which of the flutes are fragments.
