The Nazca lines are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. They were created between 500 BC and 500 AD by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving different-colored dirt exposed. There are two major phases of the Nazca lines, Paracas phase, from 400 to 200 BC, and Nazca phase, from 200 BC to 500 AD. In the years leading up to 2020, between 80 and 100 new figures had been found with the use of drones, and archaeologists believe that there are more to be found.

The Sechura Desert is a coastal desert located south of the Piura Region of Peru along the Pacific coast and inland to the foothills of the Andes Mountains. Its extreme aridity is caused by the upwelling of cold coastal waters and subtropical atmospheric subsidence, but it is also subject to occasional flooding during El Niño years. In 1728, the town of Sechura was destroyed by a tsunami and was later rebuilt in its present location. In 1998, runoff from flooding rivers caused the formation of a temporary lake some 145 km (90 mi) long filling the Bayóvar Depression. Short rivers flowing across the desert from the Andes support intensive irrigation-based agriculture.
