The geographical area known for being the last uncharted land is Antarctica. This frozen continent, primarily covered by ice, remained largely unexplored until the early 20th century. Its harsh climate and remote location make it challenging to access, contributing to its reputation as a mysterious and untamed frontier. Antarctica's unique environment supports diverse ecosystems, including seals, penguins, and various seabirds. The continent is also significant for scientific research, offering insights into climate change and glaciology, as well as serving as a natural laboratory for studying Earth's history.
