Gold Fever!!!      

Tomah Wisconsin GPAA Chapter – October 2016


Welcome to the 2016 GOLD FEVER Newsletter.  Another year, another gold prospecting opportunity.  If you have not tried to find gold, you need to give it a try.  Let us know if you need help to get started, there are many people with experience that the help you.

President’s Message

The summer is gone and soon I will have to move my panning table back inside. Sept 18 was a beautiful and sunny Sunday I combined all of my vials that I always kept to show what I got from each location into a vial for the state that it came from. I couldn't get any more in my Alaska vial the fine gold kept coming out the top. I use water in my cleanups the only way to get more in the jar would be to dry it all out and then put it in.

  With all the rain we got this summer every time I thought about going out the creeks were flooded. I worked overtime all summer now that I have a whole weekend to go out the rivers are flooding again. I got 3.6 " this week at my house but my friends just south of here got 4.5 and to the west it was even worse. Stuck at home still mowing the lawn every week.

This month is elections. Anyone interested in running for office please come to the meeting or tell someone else to nominate you. And bring your GPAA membership number with you so I can fill out the paperwork.

  The November meeting will land on Opening day of deer gun season. We will have to move the meeting date up one week to Nov. 12. I will bring it up at the next meeting and check to see if that date is available for the hall.

Tomah Wisconsin GPAA Chapter Minutes September, 2016


Old Business:                                                                                                                                                              

The August meeting was a chapter outing to park in Marshfield at Wildwood Park . It was on our weekend for a meeting so we joined them. 6 members of the Tomah club were present.

Six members came to Marshfield for the metal detecting outing in the park. It was a rainy day in the morning. We were able to hunt from 10:00 to 12:00 before the rain drove us to Hardy’s for dinner.

By 1:00 it was nice out again and the hunt continued until about 3:00. Best Finds were Richard Niemyski an 1899 barber quarter, Larry Bender a1946 mercury dime and a1944 wheat cent. Mike Fait found three wheat cents but couldn't read any of the dates.

All the rest found modern coins along with the pop-tops and aluminum foil which make this park so frustrating to hunt.

.New Business:

Next meeting October 15th at the Lagrange Town Hall at 1:00pm. It is election time for all the officers

Raffles:  None this month

 Gold Price on 9/25/16 was $1,337.10               Silver Price on 9/25/16 was $19.68

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.
