Thanks for the information. I've always found the maps of currents I've come across incredibly complex and it's something I know little about.

What you describe could very well explain the sudden disappearance of this particular driftwood. At the same time, if currents are the cause, I would assume the wood is washing up on some other shore, or perhaps it will just get bounced around for a few months until it makes its way back here.

The question remains whether the daily appearance of this wood was the norm interrupted by an anomaly or vice versa. I haven't lived here long enough to know, but it's something I plan on finding out.

One thing that I did notice at the same time the wood disappeared was that there were some extraordinary tides. And something was going on with the currents because entire beaches would be altered in a big way from one day to the next. Sandbars would be replaced by 6-8" rocks, and whole areas of beach that were normally sand would be completely covered in rock only to return to sand the next day. This was happening daily as of last weekend. I'll be spending more time at the beach over the next three days so it will be interesting to see what's going on.

The fishermen would know what's up.
