About
About Chiza Valley Geoglyphs
Steep quebrada-wall geoglyphs lining the Chiza-Suca corridor linking low pampa oases to Altiplano passes. 70+ figures include 25-m marine fish (corvina), camelid files, bowmen and large 12-m rhomboids with inset cross, dated 800-1300 CE by San Miguel ceramics in rock-shelter middens. Marine motifs 90 km inland at 1450 m encode coast-highland exchange ideology, not local fauna. Technique is mixed - upper slopes additive stone piles, thalweg terraces subtractive clearing - adapted to slope angle. Fish panels face caravan ascent, functioning as encouragement that coastal resources were cosmologically present.
Why it mattersDiagnostic marine-fauna inland proves geoglyphs encoded exchange cosmology, not local ecology.
