Ancient Inca Cairns Mystery Solved

There are rows of cairn-like pillars close to an Inca road network that stretched from Columbia to Chile. The mystery was their function. Archaeologists researched 16th century Quechua sources which pointed to calendrical, astronomical and religious purposes. Astronomers at the Atacama Array and the European Southern Observatory ran simulations of sunrises on different dates. And they found the Sun perfectly aligned with the markers. The Incas, then, broadcast their sacred power over large distances. They observed the autumn equinox at several cairn sites and found the sun rose exactly above them.
