About
About Pan de Azúcar Geoglyphs
A linear 3.5-km trail-side geoglyph string on Pampa Pan de Azúcar, a gravel plain southeast of Pintados. The ensemble comprises 12 large cleared figures — 35-m arrow glyphs, 20-m rhomboids and stylized sea-bird forms — pointing along the prehispanic Pica–Tamarugal nitrate trail. Executed by scraping dark manganised pavement to light gypsum subsoil, the figures exhibit Inca-period Tarapacá–Inca ceramics (1400–1500 CE) stratified over earlier Tarapacá sherds, indicating re-cutting during Inca road (Qhapaq Ñan) integration. The site lacks Pintados' dense additive piles, using only broad 1.5-m cleared bands visible from the trail.
Why it mattersShows geoglyph integration into Inca road system.
