Panel 1, at the extreme southwest end of the overhang at a height of 76-90cm above <br />the present ground surface (pgs), consists of series of abraded grooves comparable to those <br />frequently referred to in the literature as "tool grooves" or "tool -sharpening grooves," which <br />these may very well be (Plate 4). The two most readily apparent grooves are horizontal— <br />sloping upwards to the right, one above the other and parallel to each other. The panel <br />measures 15cm wide and 14cm high. <br />The individual grooves measure 7.8 and 7.2cm in length and 0.5cm in maximum <br />width. The cross-section of the furrows is U-shaped and they taper to points at each end. <br />Five centimeters to the right of these grooves is a series of two or three shallow, faint, vertical <br />abrasion marks ranging from approximately 3 to 7cm in length. It is suggested that the <br />grooves are the result of shaping or sharpening bone, wood, or antler tools such as awls, or <br />possibly the tips of pointed stone tools such as petroglyph chisels, however research in the <br />Great Plains suggests that, in some instances, series of abraded grooves are more likely <br />counts or tallies, or even the result of ritualized activities with symbolic significance (Keyser <br />and Klassen 2001:295-296). This panel, particularly the faint elements on the right side, is <br />being impacted by livestock rubbing up against the back wall of the overhang. <br />Approximately 5.5m to the north of Panel 1, at a height of 100 to 140cm above pgs, is <br />a piece of modern graffiti reading "Tristen, W, MF." <br />20 <br />
