Interesting Cross Design On Pond Near Marksville

Last week I had the opportunity to fly in a small plane from Lafayette to Marksville and, along the way, we noticed an interesting design on a pond near Marksville.

At first, it looked like a plus sign, but upon closer inspection, it appears to be a cross (the crucifix kind) over a curve-shaped piece of land. I don't recognize the symbol, if they are both supposed to be read together.

Is the pond on a ranch or a farm, and that is the brand for the ranch/farm?

Is it part of a family crest? Are the symbols  supposed to be read independently of each other?

What is it?

The closest community we could find (using the GPS) was Le Moyen

I wonder if the pond was built by the same people who built the fleur de lis ponds!??!
