This looks to be in a special location, must be in a remote and forest like place as it seen from the picture on both sides, moreover you already mentioned that it is having a cave. The water flow looks with slow stream seems to be different too.

But what is more getting noticed is the crystal clear and almost stationary like water that has been able to see through it what is inside till the depth where stones are visible. Pictures through your specs too looks great.

Over all it is a good post, Cheers
