Turtle Trail Near High Tide This Morning.

There was a small cut running along in front of the cliff.  It was less than a foot.  In front of that was a mushy convex beach.   Not good conditions at all.

Swell At Turtle Trail Near High Tide. This  Morning.

Notice how the swell piled up at the right side of the photo.

The area right in front of the beach is a really high energy zone.  While I feel fairly confident about my understanding of most the beach, I have some unanswered questions about that area.  It is hard to see what is going on with the sand there.

Back some weeks ago I showed some pictures that showed how waves sometimes suck sand up, but it is even harder to see what happens right where the waves crash and where the surge is greatest.

The crashing water has to stir things up there.  The downward force of the water along with the vibrations has to have an effect.  The sand there is saturated.

When soil or sand is saturated forceful downward pressure and vibrations can cause liquefaction.  Here is a link to a video demonstrating liquefaction.

Interesting.  I'm thinking that the continual pounding of breaking waves and the vibrations could cause liquefaction, which results in the separation of water and sand and the possible creation of quicksand-like conditions.

I'll probably discuss that more in the future.

A huge fossil collection was forgotten in a university bell tower for 100 years.

It was one of the worst defeats in one of history's most dramatic conquests: Only a year after Hernan Cortes landed in Mexico, hundreds of people in a Spanish-led convey were captured, sacrificed and apparently eaten.

Here is the link for the rest of that story.

The surf is smooth today.  It will be one foot through Thursday and then start to increase.  The surfing web sites are predicting 5 - 9 feet for this coming Monday.   Those kinds of predictions seldom actually work out.  We'll have to wait and see.

Happy hunting,
