Field Notes - One of the prettiest rivers in Florida is the Aucilla River. Full of dark, tannin stained water, it is the epitome of slow moving southern rivers, full of mystery and romance. On its way to the Gulf of Mexico it adds to that sense of mystery by going underground several times only to re-emerge again later. This image was taken not far above where it goes underground for the last time on its trip southward.  It re-emerges approximately three miles downstream from here.
