Many believe that the nugget gets rounded by it tumbling about. I have a large specimen that is flat on one side and I've always believed that it is that way because other objects passed over it as it stayed in place. This article confirms that for Blackwood, Australia and says:
‘A feature of many of the goldfields of Victoria was the finding of large masses of gold nuggets. They varied in size, and were not confined to any particular class of washdirt, nor with any regularity as to depth, but, from their disposition in restricted areas, certain belts can be regarded as typically nugget bearing. On account of the soft character of gold, nuggets of any size are always well rounded. This is due to the attrition of material passing over the nugget rather than rounded by rolling action. Many of the large nuggets had one side relatively flat, while the other was well rounded. Some of the nuggets were coated with oxides of manganese and iron; several had quartz attached to them, while a few were of ragged and roughly crystalline appearance.’
we are looking for information
on different types of gold ground
producing detectable gold / no gold panning
I did not go around the whole forum
but I see that there are prospectors from all over
United States, New Zealand, Australia ??
the more information we have (precise)
from different sources / better it will be ...
so, among you who already find gold
do you know the percentage of Fe2O3
and Fe3O4 on your hunting grounds
if you have answers,
please specify if the terrain is easy or difficult
to find gold
we are developing a testing ground
with mineralized lands of different origins
the goal being to have the widest possible range of difficulty
to improve performance ..
all information will be welcome
Finally got a video up that goes over and shows some the uses and benefits of lidar maps for the gold prospector and metal detectorist. I also delve into some drone usage stuff at the end of the video. Let me know what you think, and if your interested in some feel free to contact me. I will hopefully have a website up in the near future, when i do i will let everyone know here.
Thanks for watching!
Not sure if any of you knew of this site:
They have a view that shows old photos back to 1938 and topos going way back. The viewer is slow but has nice reference as you can click through the dates and see changes. It is a little hard to see but you can see some old trails, lost foundations and even early farm fields that have either been built over or trees have grown in. I use it to find some spots and I plug the gps coordinates into my phone's gps.

We've been considering some additions to the map tools on Land Matters and would like user's feedback.
Land area locations in the U.S. are typically described by their legal land description (PLSS). This is the only system that has been physically surveyed and has actual physical markers on the ground. That's why it's the system for legally describing land parcels.
All the Land Matters maps have the PLSS included as a possible display item but a lot of people (military) have been trained to use a grid to describe actual ground locations. Graticules are very much like grids but they have the advantage of following the earth's curvature, unlike grid maps. Digital graticules are capable of increasing in resolution as you zoom in to an area. These are advantages of a graticule but the use of a graticule is just like using a grid.
It's possible to use both the PLSS and a graticule when mapping so we thought we would see if some people would like the option of using a grid type mapping system. To that end I have included graticule layers on our historic places and ghost towns map to let folks try out this system and see if they would like these layers included on other Land Matters maps.
If you have an interest give it a try at the Historic Places Map. You can read more about grids, graticules and their uses on our New Projects page.
Let us know if you would like this feature added to the maps. It's a bunch of work to make those changes so we'll have to see some demand before we add these in.
