Dark-colored volcanic cones sprout from an ancient lava field in this high-resolution satellite photo. The field, known as Harrat Al Birk, covers 1,800 sq km (700 sq mi) and is the only volcanic field along Saudi Arabias Red Sea coastline.

However, many such lava fields dot the Arabian Peninsula and can range in age from 2 million to 30 million years old.
