Usually the water is not clear enough to see the entire Alligator. This was taken in a large pond, near a river, so the water is pretty good.
While not very big, about 4 feet (122 cm), it is certainly not a baby. Probably 5 years old.
He swam up to me, the trail I was on, and stopped. Watching and waiting.
You can see the shore in the lower right corner above.
He was waiting for me to get down the trail, and away. The trail is a few feet wide, with a lake on the other side. What he really wanted was to cross the trail to the lake. When I passed back later he was nowhere in sight.
