Bima sinkhole and Dahl Al -Hamam

Bima sinkhole, a photo by AdRikTa on Flickr.

some sinkholes can be found in the area of Arabian Gulf -the largest and the most famous one is perhaps in Oman -Qatar has some smaller ones
I was so much shocked to learn that in the park of Dahl el Hamam there is a sinkhole - now closed for visitors but some people managed to see it before - it is quite big -I am frightened !
Actually dahl in Arabic means  sinkhole  - they never wanted to keep it in secret ! Just we expats are ignorant !
