Dark-colored volcanic cones sprout from an ancient lava field known as Harrat Al Birk
along Saudi Arabia's Red Sea coastline. Many such lava fields dot the Arabian
Peninsula and range in age from 2 million to 30 million years old.

The western half of the Arabian Peninsula contains not only large expanses of sand and gravel, but extensive lava fields known as haraat. One such field is the 14,000-square-kilometer Harrat Khaybar, located approximately 137 kilometers to the northeast of the city of Al Madinah (Medina). The volcanic field was formed by eruptions along a 100-kilometer, north-south vent system over the past 5 million years. The most recent recorded eruption took place between 600–700 AD.
