Occasionally a wave from the two wave sets matched precisely when meeting and create a single vertical pyramid wave of 4ft+ just as it reached the beach. Great fun diving into those until getting SLAPPED down from behind while standing knee deep in 2ft waves but looking back at the beach.

• Maybe 10+ years ago, I wrote of seeing a "wave" being created that reached 10-feet high.
A similar "wave" knocked me off my 18' sailboat.
I had the temerity to leave Winter Harbor just as two cruisers ran in—
side by side.
I was midway between them, so grabbed a stainless steel shroud to hang on. I was thrown overboard anyway, and fell through a nest of lines that had preceded me into the water. My feet got snagged on the lines, and I was dragged about 100-yards before I could pull myself back on board. Did you know wearing a PFD will "aim" a firehose at your face in this circumstance? I didn't either.
I then noticed a yellow aluminum boat standing-by, who'd witnessed the "wave". I waved him (and his concerned-looking dog in the bow) off, thanking him.
• The long version appeared at this forum, but even Google can't find it.
• As we all know, trees grow from a seed. This seed apparently started growing in mid-air.
(At the very bottom of the below attachment, my black shoe can be seen under the roots). What happened to this sapling? Well, it was a Maple that was about 50-years old, died, broke off a few years later, and the stump can't be found today.
