A particularly low low tide (-1.862 ft / -56.75 cm) turned this Northern California beach into a special garden with many varieties of seaweeds, some of them edible, like kelp, nori, rockweed and sea lettuce.
I didn't harvest any seaweed the day I took the photos, but I have in the past and have some at hand for use in the kitchen.
There were also tufts of seagrass.
Note the interesting shape of the rock on the top left.
This is my contribution to edition #135 of Black and White Wednesday - A Culinary Photography Event created by Susan of The Well-Seasoned Cook, now organized by Cinzia of Cindystar, and hosted this week by Sreevalli of Ammaji Recipes.
The photos were shot in color and then converted to black and white (Lightroom preset B&WLook 5).
