Paul Kozal has trained his camera on high and low tides on the Mendonoma Coast. The contrast is amazing. The top photo shows a King Tide, a very high tide at Shell Beach on The Sea Ranch.
And the bottom photo shows the exact same place at low tide. Paul also photographed Iversen Cove's high and low tide. I will share them with you here tomorrow.
