A Mysterious Cavern in Corani District, Peru

Why was there a hole in the ground with separate entries south of Aymaña in Peru’s Corani District, 4,000 metres high in the Andes Mountains? Even guide Ulices did not know the cavern’s purpose.

The only safe cavern entry was from the side although this was not easy, for the hole narrowed substantially.

Once in, the chamber turned out to be of substantial size. The walls appeared too straight not to have been touched by humans. But why did they do it?

So, what was its purpose?

When I suggested the cavern could have been used for hunting, the penny dropped. Everybody agreed that this was its use.

After blocking the side entrance, indigenous pre-Columbians filled the cavern part way with water and camouflaged the top before attracting wild animals to the site. The animals would then fall through the top and drown. Afterwards, the hunters opened the side entry, draining the cavern, allowing them to retrieve their kill.

One less mystery to solve!
