On Long Beach, the landscape changes with the rise and fall of every tide.
King Tide
This ongoing tug of surf on land leaves unique impressions at each low tide.
Extremely low tide
Sometimes the sand is flat with a surface residue pattern left behind.
At other times, the surf carves tide-pools into the beach.
Their rills create one-of-a-kind sand drawings, as water courses back to the ocean.
Thank you Amy, for this unique challenge. All week I’ve asked myself, “what can I share that’s unique?” Once again, my answer is from the beauty nature provides.

A great choice for this theme! The patterns, drawings, carvings, … of sands are all one of the kind! All are special and unique. Thank you for sharing, Lindy！ ：）
Thank you for high praise, Amy!
Love the sand drawings you captured, Lindy. Very unique! ❤
Thanks, Olga. Hope all is going well in your world.
Yes, all is well. Summer is in full bloom which is wonderful, but I’m not a fan of the high humidity. Hope all is well with you also. 🙂
Beautiful photos. Great selection.
Thank you for dropping in and liking my post!
A wonderful study of sand patterns!
