When the tides are low, remnants of what was floating around the water during high tide are visible on the sandy beach. Through the center of the image, you can see where the waves are rolling in and out. The texture of the sand in the foreground also illustrates the constant forward and backwards pattern of the waves.
I'll have a gallery up shortly of the rest of the images from the trip. Though I didn't take too many pictures, these past few are a representative sample of what I created. I hope you've enjoyed them!
