Incised body sherd. Thickness = 7.5mm. Color: 10YR4/2 dark grayish brown exterior, 7.5YR3/0 very dark gray interior, and 5YR5/6 yellowish red core.
dStretch image (filter LDS) of the red and black figure painted on the ceiling. Scale is 20 cm. My perspective on this pictograph changed with closer examination. It has a forked tail (not two legs) and greatly resembles a barn swallow. The amorphous, halo-like black pictograph is hard to interpret - it could be an animal's head looking left with an open mouth.

Dr. Michael Fuller points to the red pictograph of six horned serpents "enechelon." that Dr. Karen Steelman C-14 dated the red serpents to AD 1030 to 1255. Photograph by Mike Chervinko on 15 January 2023 while Dr. Fuller was doing pXRF chemical analysis and Dr. Karen Steelman collected C-14 samples. This pictograph measures 96.5 cm (38 inches) in length. A drawing of the pictograph as a single serpent without the rattle tail was published by Diaz-Granados (1993:Figure 21.2e) in her dissertation; the same drawing was used in two subsequent publications (Diaz-Granados and Duncan 2000:Figure 5.39 and Duncan and Diaz-Granados 2004:Figure 12.30). In all cases the drawing is captioned as "horned serpent"; it was also termed "a metaphor for a comet or shooting star" (Diaz-Granados and Duncan 2000:202). The horned serpent identification is absolutely correct. I see six serpent heads instead of just one. The comet or shooting star metaphor actually works for several beautiful red pictographs on the ceiling of the shelter, but not this panel. Iconography of the Horned Serpent is a powerful metaphor in the ancient art of both MesoAmerican and the American Southwest (Coltman 2015).

Piece of pinkish red sandstone found approximately 20 meters downslope from the shelter. pXRF sample 32: Iron = 0.398% +/- 0.016 and Aluminum = 99.592% +/- 0.009.
View of the Groeper Shelter site. A meter scale stands vertical against a breakdown block in the center of the photograph. The 6 horned serpents are painted on the wall directly behind the meter scale. A large petroglyph of nested circles is situated on the breakdown block next to the meter scale.
This large rockshelter was formed in the St. Peters Sandstone. A small natural pool of water is formed outside the overhang after rainstorms. A cluster of red ochre and black charcoal pictographs are painted on the walls and ceiling; they are found only in the southeast arm of the shelter. The site is located on private property, not open to the public, and very difficult to reach because of its isolated location.

A second, larger serpent in faint red pigment slithers with open mouth towards the 6 horned serpents with their prey. Scale is 20 cm. DStretch image (filter YRD) of the second, larger serpent that measures 155 cm (61 inches) in length.

Large bone awl. Length = 14.4 cm, width = 1.4 cm, thickness = 1.1 cm, and weight = 12.51 grams.
The bone awl is not decorated so it seems unlikely that it is a hair pin. It may have been an awl for working with hides, but a second possibility is that it was used for giving tattoos. It is larger than most awls.

A large petroglyph with concentric circles (often considered a Sun symbol) carved into the vertical face of a breakdown block, just a few meters away from the pictograph of the horned serpents.

The black pictograph being attacked by Serpent 2 is problematic but could easily be a bird in flight.

The six horned serpents finds a close parallel in the Spiro Mound engraved shell cup illustrated by Henry Hamilton (1952: 70, Plate 110). The Spiro engraved cup with 4 horned, winged serpents could easily be thought as representing the cardinal directions. The symbolism of 6 serpents could be the cardinal directions, up, and down.

<- Lightning whelk (Sinistrofulgur sinistrum) columella that has been cut and snapped. The shell originated in the Gulf of Mexico and probably was obtained by trading/raiding at Cahokia.

Relationship of the larger serpent and six horned serpents in Groeper Shelter (23WN1177). My first impression is that it is like a proud gahi'ge (Osage, "the Great One; the Chief" based upon LaFlesche (1932:45)) greeting the dodon hintonga watsegthin (Osage, "Returning victorious war party" based upon LaFlesche (1932:37)).

A series of faint pictographs in carbon are painted near the mouth of horned serpents 1, 2, 3, and 4. In fact, each serpent has "caught" a black figure in its mouth.
