Dragon's Eye Lake

This I'm work from today. We are learning about myths and legends. We are learning about a big lake that looks like a dragon's eye. And that is what it is called. The Rogoznica's Lake, it is a lake that looks like an eye. The lake is in Croatia. What I learned today was Rogoznica's Lake,. it is a lake that looks like a big eye. it doesn't connect to any other lakes or seas. The water comes from underground, that's why it's full. But first the dragon's eye Lake used to be a cave but then it collapsed and made a big round eye. then that's when the water started to come from underground. then it formed into a big lake. That was how the dragon's eye Lake was formed.  It is very deep so it is good for divers and jumpers because if it was not there could hit the ground because it would be going really fast.And hit his head on the ground when he was going to dive. There is a Myth that there were aliens that kept on landing there every 200 years.
