About
About Sierra Pintada Geoglyphs
Southernmost Andean geoglyph group on the Sierra Pintada basalt plateau above the Atuel River. 30 cleared-line figures including tridents, sun discs, camelids and 18-m zigzags etched into dark Patagonian basalt patina overlaying light tuff 900-1500 CE by Pehuenche-Huarpe hunter-horticulturalists. At 37 S this is the austral outlier of the Atacama-Andean province, 800 km south of Taltal, proving diffusion or convergent invention in cold steppe. Technique is pure subtractive clearing with no stone piles, implying maintenance by sweeping.
C14 on hearth beneath trident dates 1020 +/- 60 CE. Unlike northern giants aligned to caravans, motifs align to Atuel gorge rim and seasonal snowline, suggesting agro-pastoral calendrics.
Why it mattersSouthernmost geoglyph field; tests latitudinal limit and diffusion hypotheses.
