Posted on April 25, 2014March 19, 2020 by jim Silk and Alan came down to Marathon to get their Advanced Open Water certs, so I drove down and joined them for the day Swimming Away Alan and Silk swimming down into Herman’s Hole Buddies Silk and Alan communicating as we descend at Tropical Rocks. Excuse Me, Nurse? A 4-foot nurse shark resting under a ledge at Tropical Rocks. The visibility was terrible and there was a lot of floating sediment in the water, so all of my shots from today stink. Reflecting Silk looks like an image out of a video game Wormz A couple of christmas tree worms on some bleached coral at Tropical Rocks. Disappointing to see how much of the coral here has been abused over time and is in rough shape.
