Thank's Steve.

Not sure what the geologic history is. But......

There are ancient beaches several hundred feet above current sea level. This layer appears to have been river bed in the distant past then covered with beach that has been raised.

I have wondered what the last cascadia event was like along this stretch of the coast.

The last event was according to scientists in 1700. https://en.wikipedia.org/wiki/1700_Cascadia_earthquake

Well the bucket of material I hauled back last time was a real disappointment.

I will hit the beach this weekend anyway weather permitting to see what I can find...

I know...... I will never make any money doing this but it gets me off the couch and is interesting to me none the less, and it is the closest gold I have available, so what the heck. 

I can think of much worse ways to spend an afternoon.

OK... Yesterdays little adventure ....

We set the sluice up in a freshet that was running out from under the cobbles that are awash during high tide.... 

There was good black sand visible in the freshet so we figured why not let ma nature do some work for us...LOL

Here is a very quick shake out pan to see what might be.....

I will finish the cleanup sometime today and post those pics later.

Well here it is... The moment I know you have all been waiting for..... Cleanup and weigh in of Fridays take.
I got the magnetics out of it but there is still a little junk in it, I figure about a grains worth of non-gold.... So we will call it approx. 5 grains +/- a little.

Not bad for letting ma nature do most of the work....:biggrin:

We got nearly 7" of rain last night here on the Oregon coast..........

So guess what? I will be heading back to my little beach tomorrow and setting up in that freshet again, it should be running strong and the weather tomorrow is supposed to be halfway decent to boot.

I will actually try to get some good pics and maybe even some video.

So we shall see what tomorrow brings.

Thank's Steve.

It will never replace my day job but at least it gets me out and moving about and I usually at least make gas money...:biggrin:

After last Friday today was a bit of a let down with only 1 grain....:angry:

The sand looked good but the freshet just wasn't up to it and ground sluicing is not the most efficient method to work.. But it's what we got in oregon since we can't run any power on the beach.... Not even an electric bilge pump recirculator unless we are above the grass line aka mean high tide line.and that just isn't practical o this beach.

I would have been better off to have hauled the sand in my gorilla cart and setup the sluice in the creek 100 yards away.

I have enjoyed reading this thread.

Can you use a hand operated pump like Allen Trees uses on his rockers?

I have thought about that and I contacted the head of the southern Oregon coast region ... He seemed to think it was OK since it is hand powered.

Problem is I need about 1100 GPH minimum to run the material through the sluice efficiently. 

I guess I could have a reservoir but that seems a little impractical due to the size and mounting required to make it work.

      Hi there RR, All this gadget is doing is mechanically classifying material into a gold pan. Nothing you couldn't do with a manual classifier over your gold pan which you could possibly get away with. I know with my sluice boxing I made & use a bucket classifier than can process a lot of material pretty quickly to feed down the box.

      I tripped over this extensive article, available as a free download. Here is the abstract:
      The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

      I have been working on this for a couple weeks.  It's a collapsible, customizable, self-contained, super light, 3D printed sluice box!  I know there are other folding sluice boxes, but none of them actually fit in a backpack, or are light enough to carry in one hand.  This solution would be EXTREMELY helpful!
      I'm on my phone trying this, so when I get to my laptop, I'll write in a bit more.
       
       
      So I'm currently in the CAD stage.  I have a guy that does 3D printing for me, and his machine is limited to 12"x12"x15" so I might have to shrink the size of the project down to fit, as I don't have access to, or can even afford, a larger 3D printer.
      I have this up on Patreon to attempt to raise some funding to start getting prototypes printed, and boost this project towards the finish line!

      I took a picture of my collection of crevice suckers for the Classifieds and figured it would make a good photo to post here for people to see a few designs old and new.
