Light-colored lapilli deposits mantle the Jabal Bayda ("White Mountain") tuff cone; a lava dome is visible within the crater. Jabal Bayda and the Jabal Abyad lava dome (upper left) are part of the 14,000 km2 Harrat Khaybar volcanic field, located N of the city of Madinah (Medina). A 100-km-long N-S linear vent system in Harrat Khaybar contains lava domes, tuff rings, the Jabal Qidr stratovolcano, and numerous small basaltic cones.
