A Wee Geologist Observes the Depth of the Intertidal Water Table

Here I am at the beach, either at Saint Simons Island, Georgia or Daytona Beach, Florida (60+ years ago).  I wasn't there to observe the pretty girls.  I was satisfying my curiosity by supervising a study of sedimentary structures in the Littoral Zone.  It is entirely possible that I was fascinated with the manner in which the hole "filled itself" with water.  (It would be at least a couple of years before I understood the concept of a "Water Table".)

Of course, I had seen a tub filled with a faucet and a bucket filled using a hose.  But here was a hole that filled itself without any "outside assistance".  (I do recall - whether it was here or not - having a "Wow" moment at a young age upon seeing that very thing.  "Where did that water come from?")
