9. Yulong Snow Mountain Glacier No. 1, Asia: Found in China’s Yunnan Province, the Yulong Snow Mountain Glacier No. 1 is one of the southernmost glaciers in Asia. Despite its location in a subtropical region, this glacier persists due to the high elevation of the Yulong Snow Mountain range.

10. Fox Glacier, Oceania: Located in New Zealand’s South Island, the Fox Glacier is one of the most accessible glaciers in the world. Its stunning blue ice formations and dynamic movements draw visitors from around the globe to witness its splendor.

These glaciers, with their immense proportions and geological significance, serve as reminders of the Earth’s dynamic and ever-changing landscape. While some continue to persist against the backdrop of modern challenges such as climate change, others have diminished over time, leaving behind a legacy of geological wonder and scientific inquiry.
