Turtles in Sand Lake

This is a picture of three turtles sunning themselves in Sand Lake (Wekiwa Springs State Park).  It's not very clear, but I was on the shore and my camera wasn't behaving properly.

They were probably painted turtles, but they were a little too far away to identify properly.

Speaking of identification, here's a wonderful site with pictures of turtles, snakes, and other Florida reptiles.  It would probably be very useful to me if I could have gotten closer to the turtles to note specific features.
