Ground-penetrating radar has been used at Puma Punku, with limited excavations conducted. What lies beneath remains largely unexplored.
Key facts corrected:
- Ground-penetrating radar surveys have been conducted at the broader Tiwanaku site, with surveys around the Akapana structure reported, but specific 2009 radar findings of "massive chambers" at Pumapunku cannot be verified from available sources.
- Excavation at Puma Punku has been limited, with very little deep excavation work completed, consistent with multiple sources noting the site remains largely unexplored.
- Specific depth measurements (two feet) and claims about unexplored chambers are unverified in available archaeological literature.
Archaeological context: Puma Punku, a 6th-century man-made terraced platform mound at the Tiwanaku site in Bolivia, has received minimal scientific excavation, leaving its subsurface features and full archaeological potential largely unknown.
