A recent excavation of a 5,000-year-old guano pile has revealed a treasure trove of archaeological and environmental evidence. Located in the Atacama Desert in Chile, the guano pile is one of the oldest human-made structures in the world. The guano piles, which are piles of bird droppings, were used by ancient people in the area to fertilize their crops.

The excavation of the guano pile revealed a wealth of artifacts, including pottery fragments and tools, as well as evidence of a wide variety of plants, birds, and mammals. The archaeological evidence suggests that the people who lived in the area 5,000 years ago were engaged in a variety of activities, from hunting and gathering to farming.

The guano pile also provided valuable insight into the local environment. Analysis of the guano and the artifacts found within it revealed that the area experienced significant changes in climate over the past 5,000 years. This evidence suggests that the people who lived in the area were able to adapt to changing environmental conditions, which helped them to survive in the arid Atacama Desert.
