About
About Lake Titicaca — Pilko Kaina Bay Submerged Temple Reef
Submerged temple reef off Pilko Kaina cove on Isla del Sol south shore of Titicaca 3810 m, where Inca-Tiahuanaco offering reef and causeway now 2–8 m under lake after Titicaca level +3 m post-Tiahuanaco aridity pulse. Tiahuanaco lakeside temple platform 10×8 m with Inca offering box containing feline incense burner, gold lamina and mullu shell now waterlogged. Excavated 2013– Delaere ULB underwater survey: stone reef causeway 120 m linking island to sunken islet with votive pottery dump 800–1470 CE. Distinct from Tiwanaku mainland entry by isolating lake-island reef temple under water — only submerged high-altitude Inca sanctuary at 3810 m.
Why it mattersOnly high-altitude 3810 m submerged temple globally — proves Titicaca lake-level history tracks Tiahuanaco collapse 1000 CE arid dip; gold lamina iconography ties Inca sun-island pilgrimage to Tiahuanaco antecedent.
