I don't know why but the name "Umm Al Jimal" is a cute name which means "Mother of the camels". Umm Al Jimal is a half hour drive from Mafraq, Mafraq is one hour from Amman to the north. This is a big ruin site with many black stones (Basalt stones). It will take you at least two hours just to make a tour. What makes this place unique is it has many cisterns.

I made 4 shots of panoramaic photos.

Shot 2 - Cistern 1
Shot 3 - Cistern 2
