Guano trade from Ilo to Tiwanaku via the Moquegua valley, as reported by Minkes 2005 and read by the proponents as exceeding agricultural need
- what the source states
- Citing Minkes (2005), the source states that llama caravans carried "the guano gathered in large quantities at Punta Coles, Ilo" up to Tiwanaku through the Moquegua valley, that this trade 'appears to have been intensified during the Tiwanaku / Pumapunku construction', and that because the raised-field system supplied fertilizer on site "They did not need the guano, because they produced on site their own fertilizer."
- what we infer
- Mine: the trade route and its intensification are Minkes' (second-hand here); the claim that quantities exceeded agricultural need is the proponents' assertion without figures. Supports the descriptive part of GEO-C581 weakly; the 'did not need it' inference is unquantified.
- limitations
- Minkes 2005 not read; no quantities of guano traded are given.
- 'Intensified during construction' is undated in the source.
