In this Feb. 12, 2020 photo, residents walk past signs that read in Spanish “Intangible archeological zone. Entrance prohibited,” left, and “Danger. Works.” where workers digging for a natural gas line ran into ancient bones and vessels from a previous Inca culture in the Puente Piedra neighborhood of Lima, Peru. About 300 archaeological finds, some 2,000 years old, have been reported over the past decade during the building of thousands of kilometers (miles) of natural gas pipelines in the capital.
