The 37th Parallel South is an imaginary line of latitude that circles the Earth at 37 degrees south of the equator. It runs through several countries, including Australia, New Zealand, and parts of South America. This parallel is significant for various geographical and climatic studies, as it often marks the boundary between different climate zones. In the United States, the 37th Parallel South passes through states like California, Nevada, and New Mexico. It is notable for its diverse landscapes, including deserts, mountains, and forests. The line has also been referenced in popular culture, particularly in relation to UFO sightings and conspiracy theories.
