Before I reveal the winner I'm going to explain how Jones Lake was created. Like I said, this is somewhat of a trick question. Nobody knows how it was created. Jones Lake is a water filled Carolina bay.
Carolina bays are eerie wetland depressions scattered across the Eastern coastal plain from southern New Jersey to northern Florida. Most are perfect ovals, ringed by ridges of sand as high and dry as their interiors are low and swampy, and they are largely impenetrable, surrounded by or even filled with walls of shrubs and tangles of thorny plants. All Carolina bays are aligned the same direction, from northwest to southeast. They have high rims of white sand on the southeast side.
There are many theories on how they were formed. From metors, comets to ocean currents and wind patterns.
I think the comet is what caused them. If metors was the cause there would be some materiel from the metors left behind, but none have been found. I think the Earth passed through the tail of a comet. Since they are mostly made up of ice there would be no material left behind. Here's a great website that goes into great detail about each theory.
Carolina Bays
Now on to the winner. Like I said your answer didn't have to be exactly right since it wasn't know how the lake was created. I was looking for you to tell me that Jones Lake is a Carolina bay. And there are many theories on how they were created. Out of all the answers I picked the one that best explained this. I only got 3 replies. Since it would have been easy to just type Jones lake into Google and cut and paste the answer from a web page, I thought I would get more people trying to win.
Here are the three replies I got.

It was created by a meteor shower,and a meteor/meteors made the crater.

The depressions in coastal plain of NC are called bays or bay lakes and one theory on their formation is through a meteor shower thousands of years ago.

Scientist have pondered the origin of the lake and many ideas have been introduced but none are widely accepted. Jones lake is actually a bay lake that is roughly 2 1/2 miles and very shallow (about 8-9ft deep).
Some of the ideas: are meteor activity
underground springs
wind/ wave action
They are still theory though. Nothing has been totally confirmed as the origin.

I think it's clear who the winner is. Superimposedhope explained it the best.
Since jhaluska knew the answer about the turtle I was pulling for you.
Well Joe send me a pm, and I'll mail you your prize, one D.capensis seed.
Edit: Did I mention that you have to pay the $25 shipping fee?
