The Southern Alps (Kā Tiritiri o te Moana) is a mountain range that extends along much of the length of New Zealand’s South Island. This Overview, captured by an astronaut onboard the International Space Station, shows the range’s highest elevation areas including Aoraki / Mount Cook, the nation’s highest point at 12,218 feet (3,724 m) above sea level. To the east of the Southern Alps is a series of turquoise glacial lakes — the three seen here are Lake Tekapo (top), Lake Pukaki, and Lake Ohau (bottom).
