Four views of the tidal basin from the top of the tower.
A tidal basin is land that was not covered by the tides, but is man made to accept the tides. Robinson preserve was a 487 acre farm left to the state by the owner, with instructions in his will that it would be turned into a tidal basin to preserve for the Eco system and to create a bird preserve.
NO, I did NOT look straight down, I shot the below straight down by standing back and shooting blind.
Below are shots of the tidal basin from the ground. For more info and a slide show on the Tidal Basin CLICK HERE
