Ecosystems in Iran

Two Chinese dragons guard the caves of this medieval temple in Iran.

The hottest, driest, and most scenic desert on Earth.

Hundreds of stones dangle from barren trees in the middle of the desert.

This vast, water-filled underground labyrinth can only be toured by boat.

This 12,000 year old Iranian cave village has been continuously inhabited for over 3,000 years.

Modern-day cave dwellers carve elaborate homes out of volcanic debris.

One of the world's largest salt caves is filled with fragile salt sculptures, salt rivers, and huge salt megadomes.

Salt cured mummies continue to turn up in this Iranian mine.
