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.

      Just finished this project, figured somebody might like it around here.

      My sister ran into a fossiker when out camping who was having an issue with tiny shot while finish panning.  He was sucking the shot into his snuffer bottle when trying to collect the gold.  Any suggestions?  I have a feeling he's not the first person to be annoyed by this.

      Does any place still make and sell the rubber Knudsen bowl liner? Google seems to just lead to a bunch of spam pages. I acquired an old bowl and the previous owner thought there was a store in Reno that made or sold them but I haven't had any luck locating said store. 
      Also semi-related I am rebuilding an old jig, never used one before, and I was wondering what people use for shot? Do you just buy steel shot in bulk like from an ammo place or is there something cheaper and better to use specific to jigs? I see tungsten shot available for jigs but it's the same density as gold more or less so I'm having trouble seeing how that would work, especially if I want to save the black sands too. I'm curious what people use here?

      I ran 2 Ozt of my -50 mesh, black sand concentrate through the Blue Bowl.  It came out to .5 gram.  This was 2 oz dry concentrate off the top of the container, I suspect the bottom my be richer after all the jarring around for the past 2 weeks.  I'll send the Blue Bowl tailings and about a couple lbs of concentrates to Rege in PA to see what his Miller Table can do.  If I could fill the back of my truck with this stuff it might be worth something, but as it stands not really a game changer.
      Still waiting on Rokon parts, then back to Gold Country.  I've got a new plan, of course.  118 degrees here in Sunny Yuma tomorrow, but it's a dry heat.  Yeah great!

      I've been trying to come up with a unit to recover gems dry, but finally realized that the "granular convection" problem can't be defeated. In the process of building and trying various ideas, I came up with this unit. While the dry recovery of gems requires some very tight classifying, and thus isn't practical, I tried it for gold, and was simply amazed at its abilities for heavy metals. I have tried it on all sorts of raw materials, running bank feed at roughly 2" minus, and have yet to find a material it doesn't work on to one extent or another.
       I ran it dry...no water, on damp material at the LDMA Blue Bucket outing near Baker, Oregon a few weeks ago, and recovered flour and black sand from old tailings from previous outings. Running wet, the day before, on new material I recovered very near 100% on black sand and gold in front of several witnesses. They suggested re-running the tails, and zero black sand, or gold was found. Last weekend I attended a local club outing at Salmon, Idaho. The material was a heavy clay with lots of rocks....not a fun material, at all. At the common dig, one of the guys next to me, running a highbanker, mentioned that my little unit was handling the clay really well. I was the only person running 2" minus directly into the machine, and the rocks were agitating the material so the clay broke down, and the rocks were mostly clean before they went out to tails. The day prior to the common dig I went down to the locale the common material had been hauled from, and ran the material dry. This was  a nasty, damp material. I expected nothing and was surprised to see both black sand and gold when I did the cleanup. Certainly I lost quite a bit, but any recovery working dry from damp material is an accomplishment. This unit works wet or dry. Very little dust running dry. Very low water requirement when running wet...roughly 50 gallons/hour.
       The full utility US Patent has been applied for.
       You can see the prototype running at Bonanza Bar on the Snake, along with pics of the recovery here:

      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.
