Why do flooding and fires affect gold concentration?
You may have heard me mention that floods are the primary agent of movement for concentrating placer gold. In fact water moves all that gold, even in the desert.
What is possibly the most fascinating part about this is the fact that erosion of land and riverbed is strongly affected by the speed of water moving over it.
Plants act as a natural sponge and a source of braking friction to slow water motion and retain the top layers of soils on hills and canyons.
Nature has its own way of removing grasses and organic matter from the hillsides, it’s called fire. Fire is one of the main causes of mudslides and flooding in the world today.
Once the grassy erosion buffers are removed from the hillsides, there’s little to stop the motion of water. Once the soil moves, the rocks and gravel buried deep inside give way and quickly slide down toward the deepest spot in the canyon.
From there, they slowly migrate toward the ocean along with the gold trapped in it.
What does this mean for you?
This means that one of the best times for you to go look for gold can be the year or two after a big brush fire. Assuming you can gain access to that gold site.
It also means that the gold will be recharging the classic locations for gold to concentrate. I discuss a lot of this concentration process and how to recover gold in the “Gold prospector’s bonanza club”: http://Hunting4Gold.com/get/gpbc/
Of course it goes without saying that you need to fill in your holes and use best prospecting practices because the fire cleared brush also means it’s a lot easier to see what gold prospectors are doing in the distance.
Until next time,
