is located immediately below the bluff overhang. The fill of the occu- 

 pation area is a rich humus mixed with fallen sandstone fragments 

 from the bluff. The area has been disturbed by rodent activity, 

 picnickers, and the activities of local enthusiasts who believe that the 

 petroglyphs are a treasure map. For this reason, no cultural stratifi- , 

 cation could be distinguished. 



EXCAVATIONS 



The entire area beneath the bluff overhang was laid out in 5-foot 

 squares (fig. 62). Each of these squares was carried down to bed- 

 rock, maintaining arbitrary 0.5-foot levels during the excavation. A 

 total of 13 squares was excavated. 



The 0-foot to 0.5-foot level yielded the following artifacts: Two 

 small triangular points; a large expanding-stem point; the tip of 

 another point or blade ; a slender drill ; portions of three end scrapers ; 

 two flake scrapers; three cord-marked, grit-tempered potsherds of 

 Aksarben affiliation ; one thick, plain, grit-tempered sherd ; one sand- 

 stone shaft smoother ; one cupstone ; one stone hoe ; one hammerstone ; 

 one core ; and one plum seed. 



The 0.5-foot to 1.0-foot level yielded the following : One large ex- 

 panding-stem point; two blade or point fragments; one Aksarben 

 sherd ; one shell-tempered sherd ; and one fragmentary limestone celt 

 or hoe. 



The 1.0-foot to 1.5-foot level yielded the base of a large, expanding- 

 stem point ; the tip of a large blade ; a large, smooth, shell-tempered 

 sherd ; and a piece of charred vegetal material. 



The 1.5-foot to 2.0-foot level yielded the tip of a large point or blade 

 and a complete point of the small, triangular, "late horizon" type. 



The 2.0-foot to 2.5-foot level, present in only three of the squares, 

 yielded only one artifact, a modified flake. Charred wood also ap- 

 peared in this level. 



Unworked flakes, animal bone, and other refuse were apparent at 

 all levels. 



PETROGLYPHS 



Several petroglyphs, both incised and pecked, were fomid on a 

 large sandstone slab which once formed a part of the overhang of the 

 shelter. From the orientation of the petroglyplis it seems evident that 

 they were made at a time before this slab had broken loose from the 

 bluff face. If the slab were restored to its original position, the 

 majority of the figures would be upright and on the outer face of the 

 overhang, while one of the figures (pi. 53, «, 5), a warrior with a bow 

 and arrow, would be on the undersurf ace.
