Along the Black River in the Amazon, also called Rio Negro, at a location called Ponta Das Lajes in Brazil, a drought in the region has dropped water levels low enough to reveal previously discovered petroglyphs (rock carvings) of human faces. But the water line has dropped even further since 2010 and archaeologists recently discovered more ancient history, dated between 1,000 and 2,000 years old (pre-Columbian South America). A sculpture of a human face was carved into one of the slabs of rock, which is unlike the other carvings at the archeological site. And other carvings in the rock at the location indicate their use as a whetstone to sharpen tools and weapons. Due to the harsh conditions of the Amazon, much of the archeological evidence of previous inhabitants has been lost to time (or has been difficult to locate), but continued findings like these reveal that the region was once host to large civilizations.
