Have you heard of Cochasqui? I hadn’t. This piece from Ancient Origins talks about a site not too far north of Quito:
The archaeological sites in Ecuador are often overshadowed by more popular locations in neighboring Colombia and Peru. However, archaeology enthusiasts have a wealth of options including more than just well-known Ingapirca to admire. Take for example the huge, 83.9-hectare site of Cochasqui, where pyramids and sacred animals patiently remind us that Ecuadorian archaeology holds more secrets than most people recognize. The debate is on: was Cochasquí a home for Quitu Cara elite, an astronomical observatory, a fortress, a sanctuary, or did it serve some combination of functions?
The pyramids were created with cangagua (a volcanic rock-like material). Scholar say the 160kg (352.74 lbs.) cut blocks of rock were softened with water and then cut using harder volcanic rock tools (the site was inhabited before the Iron Age).
