Hi all,
I 'm sorry I had to cancel the
December meeting but the storm did come in just as they predicted. Though the
roads were fairly clean in the morning there were still slippery spots and it
didn't pay to endanger anyone. We will try again in January. The gift exchange
will go on as planned. I hope you all can make it and we don't get another snow
storm or ice storm like on Christmas.
I had my
cataract surgery on Dec 22 now 4 days later I still don't have perfect vision
but it is better than it has been since last march. Night driving has improved
200 percent, no glare. I go back to the doc on Friday hope for more good news
and better eyesight as the days go on. This was the best Christmas gift I could
have gotten.
I talked
to Larry Bender the night I cancelled the last meeting. He still has lots of
pain and my not be able to join us for quite a while.
Cold
weather and surgery has shut me down as far as panning is concerned. I have
received a couple of calls from new prospectors about what equipment they should
buy, i told them to look at the Keene sluces but if they could afford it to
check out gold hog matting. I keep hearing good things about gold hog it is just
more costly and I like my Keene.
Hope you
all had a great holiday. Mike Fait

The Helical Flow Effect
What
Impacts Helical Flow?
Now precisely understanding helical flow itself, like so many things concerning
hydrodynamics is not so much science for given creek bed as it is art. It's the
art of spotting where the average flow would've taken the gold including all the
obvious natural flow variations that impact the flow and where it deposits your
gold. Below I list some things that will impact the accuracy of your helical
flow estimation:
Turning flow
- Of course, as I mentioned earlier helical flow will change based on turns and
the type of turn. For example the vortex flow formation depends on how sharp and
even the turn is and how deep the creek bed is, along with boulders or other
obstacles in the flow.
Straight flow
- As the turn begins to straighten out helical flow will sweep things into the
centerline. Of course between turning and straight that line is going to cross
to mid-stream in a kind of S-curve from the side where the curve is bent to the
middle as the stream flow straightens. Notice the gold line doesn't go
immediately to the center line, instead it sweeps slowly from the outside to the
middle and then as the turn bends the other direction it will trail over to the
other side. This pattern is typically shown is an S-curve across the centerline
and down the middle if the stream is straight for a sufficient distance. Of
course what is sufficient depends on the speed and uniformity of the flow
through that region.
Notice how often things about flow and gold deposits get qualified with a
qualitative "it depends" factor. It's important to note that the science of
understanding water flow is by definition approximate at its best. In a real
world setting, this often means you're better off just getting a feeling for
what the flow may do and then use that understanding to form your hypothesis for
where to take your gold samples. Then use the samples to prove that your
hypothesis is true or false by measuring the gold in your samples.
Key objective:
What does the gold sample predict about where to sample next? Start by sampling
in the areas that your flow based hypothesis or educated guess predicts the gold
will concentrate. This hypothesis is based on your best guess using a bit of
art, science and a whole lot of experience. You'll get this experience and
ability when you have tested enough samples. You'll learn this stuff best by
prospecting more and taking more samples.
Large obstacles
- Objects such as boulders, cliffs and bedrock obstacles that jut out into the
creek and other flow disruptions of sufficient size will definitely affect
helical flow and the formation of helical flow which in turn affects where gold
will tend to concentrate. In fact obstacles and their flow disturbing turbulence
will impact whether a pay streak will form at all. Keep that in mind if there's
a big disturbance in the high water flow. That disturbance may easily alter
where your helical flow would tend to deposit gold. For example a large boulder
will tend to form a great big trap or sweeping eddy current and break up the
helical flow at the same time. A big trap like that will tend to trump the
S-curve and the linear gold placer paystreak rules given earlier. At that point
you're looking for a big placer pocket or downstream gold trap.
Stream speed drops
- As the stream-flow slows down the gold will tend to drop out of the flood flow
at the point where the flood speed starts to decrease. These will also disturb
the existing vortex flows if any exist. Look for sudden widening or deep pooling
areas. Anywhere a fish would like to feed as food drops out of the flow. This is
also where cobbles and gravel tend to collect in flood conditions. Avoid smooth
bowls as your gold will tend to blow out of those in a rushing flood.
Why Do Helical Flows Sweep Gold?
The vortex formed in helical flow contains energy. Helical flow energy takes the
form of the rotating and moving mass of water and debris. Much like the prop
wash of a boats propeller, this dynamic rotating water power energy will move
things that it pushes against. When a stream of water and bedload entrained in
it moves, it's actually moving a fair amount of mass per unit volume. That flow
contains energy in the form of mass and speed. This energy, when restricted to
the creek bed, will tend to take on certain flow patterns based on friction and
flow restrictions. One of these patterns is the formation of a helical-flow; of
course there are other jet patterns and turbulent eddies that can take place as
well, especially when flow-disturbance and turbulence are involved.
For helical flow the energy is contained in the downstream movement of mass and
in the sideways rotation of the complete stream bedload and water mass. It's a
rather complicated thing but just knowing that it behaves like a massive
corkscrew is good enough for what we do here.
The sweep of bedload material contain your gold is both along the flow (in a
line downstream) and partly sideways to flow (rotating perpendicular-to-streamflow)
that means gold will generally move diagonally until it finds a trap or lower
speed drop point. Just keep in mind
speed changes as the corkscrew turns based on how much volume of water must flow
through a given zone along with friction.
If more water has to make it through a given amount of time the water's going to
speed up, if it's less volume per time then it slows down. That slowing action
is what drops the gold. As I mentioned earlier, you'll want to look for wider or
deeper transition regions in the high water flow. These are places where it will
slow the flow "just enough."
