About
About Gran Paititi — Pusharo Lagoon Lidar Block West at Madre de Dios Ouest (Manú Ouest)
Third Gran Paititi lagoon variant west of Pusharo east ridge lidar block already in database (gran-paititi-manu-basin-pusharo-lidar-block) and Pusharo west terrace, where a 1.2 km lagoon-edge levee 0.9 m high with two 15 m raised mound-islands in palm swamp behind lagoon now lies under montane palm canopy. 2022 SERNANP lidar snippet showed levee rectilinear with 15 m mounds promoted as 'lagoon pyramids' but ground check found no ceramics — only 1600 CE charcoal hill burn and termitary hill. Hypothesis contested: levee is palm swamp drainage levee 900 CE not city wall, mounds are natural earth oven or termitary. Treated hypothetical pending larger lidar.
Why it mattersTests third Paititi lagoon variant: levee rectilinearity proves drainage geometry but not city wall; mound-islands are termitary not pyramid; clarifies Manú lagoon geoarchaeology and palm swamp field vs city conflation.

Theories
- 01Paititi lagoon levee is palm swamp Raised field drainage for motacú palm 900 CE

History
How it came to be
- Built
- levee if cultural c. 900 CE palm drainage, mounds termitary or oven, if natural Holocene levee
- Period
- Hypothetical Late Horizon (?) palm swamp levee 900 CE or natural
- Culture
- Hypothetical Inca lagoon city (unvalidated) / pre-Columbian field (?)
- Purpose
- Gran Paititi lagoon city hypothesis — levee and island mounds as lagoon city claim vs palm drainage
- Abandoned
- palm swamp persist leaf litter
- Rediscovered
- 2022 SERNANP lagoon lidar snippet west Pusharo
- Excavation
- Unexcavated
c. 900 CE (?)
Palm levee 1.2 km built if anthropogenic drainage — else natural levee
1600 CE
Charcoal hill at lagoon edge — if cultural mound building, else burn
2022
SERNANP lagoon lidar + ground truth finds levee 0.9 m but no sherds
