Jupiter Beach down to bedrock!

Not really... but thought the beach replenishment shots were pretty interesting I know it's been filled a few times over and probably mostly canslaw from the inlet but the parts where the excavator digs out before they refill the area with inlet sand would be tempting

Whenever the sand movement is man-made like that, it's rarely ever any good. For example: They might have removed down to 6 ft. down, but that's not the same as when mother nature removes to "6 ft. down". Because when mother nature is doing it, then : Whatever coins and objects (the heavier metal items) that were within that 6 ft., get compressed down into a single few inches at-the-bottom. Ie.: All the lightweight sand can be taken out, leaving the heavier objects behinds. Like a giant sluice box or riffle board fashion. As opposed to a tractor, which is carting off all the objects that were in that 6 ft. Am I making sense ?

Stratification, Tom's right it not enough to just move the sand. In my neck of the woods they're talking about retreating from the beach and allowing the sea to do it's thing on an old popular beach, rather than attempting to replenish.
I'm fingers and toes crossed they do it. The finds will be epic.

Yes indeed, I feel ya. One caveat IMO would be if the bedrock was really at 6.5ft down, and they scooped off 6ft of dirt AND the gold etc had already settled down to bedrock in previous erosion cycles but been out of reach

That is contributing to global warming, Stop the heavy equipment!

On a different FL cam I also found this offshore sand retreat from way back when. Looks like Caribbean type water with that clarity Reckon a goodie or 2 was found around those rocks, hopefully the leaseholders got to it 1st. Gen pop can't snorkel detect on 1715 beaches right?

Yes. That ^ ^ would be the exception. And yes, there are beaches that have a true "bedrock". Which is either stone/rock type, or a very compressed sandstone type layer. That, yes, prior storms can leave everything in a single strata/layer at.

Not very likely that man-made digging (for usual dredging type work) just "coincidentally" goes down to *just* that level, but : Yes, it could happen. Good point.
