Alan Westfall makes a digital image of the large pictograph of the Atlatl hunter/warrior. Thomas Mercer makes a digital image of the dog pictograph. These pictographs are very, very faint. That is not unexpected with they date to the Archaic Period (6000 - 1000 BC) or Woodland Period (1000 BC - AD 900).
-----------------------------------------------------------------------------------------------------------------------
The animal beneath the two atlatl hunters/warriors seems most likely to be a dog. A short red dash behind the animal may have been another hunter. If the dash behind the "dog" is a continuation of its tail, then it is more likely a panther which changes the whole reading of the panel. The dog interpretation seems most plausible.
Analysis of the "dog": Reading 23 --- Iron = 12.152% +/- 1.441, Silica = 53.77% +/- 6.76, [remaining % would be Magnesium but its % was not recorded]
Reading 46 = Zirconium = 19.9 ppm +/- 8.16, Iron = 581.82 ppm +/- 51.8, Barium = 210.78 ppm +/- 47.9, Strontium = 14.8 ppm +/- 2.96, Rubidium = 3.68 ppm +/- 1.9.

Reading 49 -- Zirconium = 41.13 ppm +/- 8.9, Iron = 193.52 ppm +/- 37.81, Barium = 142.17 ppm +/- 49.24, Strontium = 45.94 ppm +/- 4.02, Rubidium = 4.14 +/- 2.

Mark Leach points (not touches) to a group of abstract pictographs that may represent a group of atlatl weights (bannerstones) positioned on the handheld throwing stick.

An outlined pictograph is positioned beneath the dog pictograph. It may be from a later (Mississippian Period) because it does resemble some of the outline pictographs in Picture Cave.
Reading 25 --- Molybdenum = 0.604% +/- 0.219, Niobium = 1.667% +/- 0.305, Zirconium = 0.349% +/- 0.089, Iron = 2.667% +/- 0.521, Aluminum = 6.443% +/- 2.276, Silica = 44.353% +/- 3.929, Magnesium = 43.793% +/- 4.07.
Reading 44 -- Zirconium = 9.75 ppm +/- 6, Iron = 332.81 ppm +/- 31.64, Titanium = 1440.25 ppm +/- 559.84, Strontium = 13.99 ppm +/- 2.2, Rubidium = 2.18 ppm +/- 1.35.
The surprising amount of Titanium can not be easily explained. There are commercial Titanium deposits in Madison and Iron Counties, MO.
Faint red pigment pictograph and DStretch (filter YWE) situated approximately 13 meters right (west) of the Atlatl Hunter pictograph. In terms of proportion - it is in a correction ratio for a mule deer to the hunter. The prominent ears suggest a mule deer in contrast to the common white tail deer found today in Missouri. Douglas Porter, a colleague in rock art research, identified this pictograph during his trip to the site. It was not recognized in my previous visits, so it does not have a pXRF chemical composition. The faint nature of the pigment make it a poor candidate for pXRF analysis. Frank Magre recorded the mule deer in a sketch that he made in 1961; Carol Diaz-Granados (1993:514 - 5, Illustration 70.6.7) discussed the pictograph in her dissertation and characterized it as "a deer with long ears."

White Rock Bluffs Pictograph Site (23TE01)
A pictograph (painted rock art) site called White Rock Bluff has been known since the 1930s. The site is situated on private property and is not open to the public. The pictographs are painted at approximately eye level along 250 feet of a white sandstone bluff. The White Rock Bluff site was reported to the Archaeological Survey of Missouri by Mr. Thomas R. Brown. A report on the site was prepared by Frank Magre that included the local tradition that the last Native Americans living in Texas County told the pioneers that the pictographs were ancient, before them. Magre noted that Gene Diesling visited the site several times between 1937 and 1939. I first visited the site on 1 June 2012 and returned on 9 June 2021; here are the results of that fieldwork. I returned on 13 January 2023 (yes, Friday) with Dr. Karen Steelman to assist her in taking a C-14 sample to test the theory that the Atlatl Hunter pictograph was painted during the Archaic Period (7000 to 1000 BC).

50 cm left of the Atlatl hunter/warrior is an abstract design that reminds me of a bundled object (medicine bundle or burial). Beneath it are two nested circles.
Analysis of the diagonal of the "abstract design": Reading 18 --- Niobium 0.575% +/- 0.176, Iron = 5.735% +/- 0.683, Silica = 29.012% +/- 2.413, and Magnesium = 64.523% +/- 3.14.
Reading 50 -- Antimony = 28.29 ppm +/- 11.53, Zirconium = 13.32 ppm +/- 7.01, Iron = 932.9 ppm +/- 54.4, Manganese = 56.24 ppm +/- 32.64, Barium = 278.52 ppm +/- 42.09, Strontium = 18.36 ppm +/- 2.68, and Rubidium = 3.36 +/- 1/63.
A very significant panel at the White Rock Site (23TE01) includes two atlatl hunters/warriors and an accompanying animal is situated several meters left (west) of the large Atlatl hunter/warrior. Handheld xrf analysis confirms that the pigment is mainly iron. The fainter pictograph has less Iron. There is a small amount of Iron (0.902%) naturally in the Roubidoux sandstone formation; the white color of the sandstone is probably because of the low natural Iron content..
