I recently read about how the Incan civilization navigated the Andes Mountains and understood the weather patterns. Can you explain how they used the wind to identify different altitudes?
The Incas relied on a system of wind indicators, such as flags or smoke signals, to help them navigate through the mountains. They would use the direction of the wind to determine the altitude at which they were located. For example, if the wind was blowing from the west, then it would be assumed that they were higher up in the mountains. Conversely, if the wind was blowing from the east, then they would assume that they were lower down in the mountains. This allowed the Incas to accurately gauge their location within the Andes Mountains.
