Here is a shot I took of some cypress knees on the edge of the canal at Lake Waccamaw. You can read more about cypress trees in general here and cypress knees in particular here. I did a little research and found out that these are used to make art. They are highly desired for carving statues and such as this. The purpose of cypress knees has not been determined. Some think they serve as anchors for the tree, and some think they serve to provide oxygen to the underwater roots.
There are several species of wildlife that are only found there in the entire world. Unfortunately, it’s a little difficult to get pictures of them, since you find them mostly in the murky depths. That doesn’t require Delta machinery, but it does require a wet suit and a fancy-dancy camera, so I will continue to content myself with top-side shots.
