The video explores the mysterious Carolina Bays, oval-shaped depressions found in the eastern United States. These features, ranging from New Jersey to Florida, are ecologically significant and home to various species. Scientists have proposed several hypotheses for their formation, including meteor impacts and ancient lakes. The most supported theory suggests they are remnants of thermokarst lakes formed during the last Ice Age. The video also explains the optically stimulated luminescence technique used to date these formations, revealing their age to be around 92,000 to 95,000 years.
