While travelling in Turkey, we came across this natural big hole filled with fresh water. The size is amazingly big when compared to the two men standing near the edge or the flock of white birds flying over the water. Could it have been a crater of an extinct volcano? we don’t know. . . . . . . . . . . . . .. . . . . . …….
PS I have tracked it down. This is the Obruk Han Golu, doline (sinkhole) below the caravansary near Cappodocia .
Wow, for some reason I pictured Turkey more forested. It’s neat to come across these unusal topographies though. Yes, perhaps dormant volcano, it’d be interesting to find out. Might get an idea if looking down from space or higher up.
This is a picture taken from above and it was so big that I could just got it into my photo. Will be interested if readers can give me a clue as to what it is. Regards, Michael
Makes me wonder, where did that come from??
A reader has suggested the hole was formed by meteors showering the earth. Need to consult a scientist / geologist. Thanks, Michael
That’s a big swimming hole. Where in Turkey is it?
Hi, I think this is not far from Cappodocia. Regards, Michael
wow there seems to be a weird vibe around there, kinda like meteors showering the earth when the dinosaurs reigned supreme… :S
You could be right. I would like a response from a scientist / geologist. Regards, Michael
Interesting! I had been to cappadocia…..did you take this pix on a balloon ride?
Hi friendlytm, no, the pix was not taken from a ballon. The surrounding ground, from which this pix was taken, was a lot higher than the hole. Michael
I must admit this depicts a big hole… but where did it come from…??? looks like it could be a quarry, has it a name that one might be able to Google??
I thought about it. The hole was circular / oval with overhangs at the top, almost vertical face and no apparent access (except narrow footpath) from the surrounding ground; not sure it is a quarry. Unfortunately, I don’t have the name and more exact location of the hole to follow up further investigation. Have a great weekend!
Could this be a massive sinkhole ?
Hi Kong, It is quite possible. There maybe an underground stream eroding the seemingly limestone formation so that an underground cavern was initally formed. The top of the cavern has since collapsed, leaving a hole. There may still be other possible explanations. Regards, Michael
This looks rather isolated. How did you get there? Did it take much hiking?
Hi Paula, We got there by car, in fact, we were on our way to Cappodocia. There wasn’t much hiking at all, the “hole” area was depressed when compared with the general land formation. Regards, Michael
Very interesting post.
Thank you Northern Narratives!
Once again, a great photo, Michael!
where underneath the water some secret hideaway is hidden 
Have a wonderful weekend! 
It looks kind of surreal with the tiny people next to it… like it could be a scene in a James Bond movie
Like what you say; very imaginative. Could be an ideal place for a movie! Have a great weekend! Michael
I suspect this is an abandoned quarry.
I would have agreed to it but I note there are no construction access down to the hole area, the hole has an almost vertical face with overhangs near the top. From research, this area had lots of volcanic activities in the “Alpine” period. Regards, Michael
Got a more specific location? This is probably documented.
Hi Jeremy, I have now tracked it down. This is the Obruk Han Golu, doline (sinkhole) below the caravansary near Cappodocia. Regards, Michael
Was it close to the ocean? We went to a sinkhole in Oman that was enormous like this and it was very close to the ocean. The water in it was fresh, but there were tunnels that linked to the ocean.
Hi, this is not close to the ocean. I have tracked it down. This is the Obruk Han Golu, doline (sinkhole) below the caravansary near Cappodocia . Thanks, Michael
It’s a pretty amazing sight. Thanks for sharing.
I have nominated you for The Reality Blog Award http://luccav.wordpress.com/.
Hi cav12, thanks so much for the nomination. I have decided not to pursue or accept any nomination / award during my retirement and for this reason, I have already turned down all similar awards. Knowing that my blog is read in many places of the world is already my biggest reward. With regret, I have to decline the nomination. Thank you once again for the nomination which is very much appreciated! Regards, Michael
No worries and thank you for getting back to me:)
You are welcome!
That’s fine Michael. Thank you for replying
Thanks again!
Incredible–I’d have sworn it was human-made!
Having seen the hole, I was quite sure it was natural but was intrigued by the process that created it. Nature is just incredible!
Wouldn’t that hole have to be fed by an underwatwer stream of some sort?
Either way, cool shot… Very cool!
The hole is so low down that it could be below the water table in the surrounding area or that it could be fed by an aquifer. Regards, Michael
Wow I love it! It’s a wonderful idea for the challenge
Thank you for the always kind comment!
Although I’ve been in Cappadocia, I never heard of this lake.
Anyways, I miss my country
If u have more photos and share them in your blog, i ll be grateful 
Regards
Kerem
Hi ckn, I have one post on Cappodocia- the Land of Fairies. I have quite a few photos of Cappodocia and will consider writing up further posts. Regards, Michael
I like when there are unusual entries for the challenges … this is one of them.
Very nice
Hi Isadora, I love to share this image of the big hole with others. When I first submitted it, I have no idea as to how this big hole was formed. Thanks for the comment! Michael
