In October 1973 residents of San Carlos Uruguay witnessed a bright luminous object descend from the sky and briefly touch down in a rural field.

The craft remained on the ground for several minutes before ascending rapidly and disappearing.

The following day investigators and locals examined the site discovering a circular area of scorched grass along with three distinct indentations in the soil arranged in a triangular pattern.

No footprints or tire tracks were present and the burned vegetation showed no signs of conventional fire or chemicals.

Official reports from Uruguayan authorities noted the physical traces but offered no conventional explanation.

Multiple eyewitnesses described the object as metallic and silent during its brief stay on the ground.

This case stands as one of the better documented landing incidents from South America in the 1970s with physical evidence preserved for study.
