My friends and I took a trip to Arequipa in southern Peru to visit the Toro Muerto archaeological site three hours' drive from the city. It was fascinating and mind-blowing to see how the local people communicated their thoughts and prayers in ancient times. Watch Robert Sulla, an official guide describing some of the petroglyphs.

Wikipedia: Toro Muerto (English: Dead Bull) is a collection of ancient petroglyphs in the Peruvian coastal desert, found in the Castilla province in the region Arequipa in Peru. The site contains some 3000 volcanic rocks with petroglyphs dating back to the Wari culture, active from 500 to 1000 CE. The Wari (Spanish: Huari) were a Middle Horizon civilization that flourished in the south-central Andes and coastal area of modern-day Peru.
