Occurrences of Placer Gold
While it is true that gold might occur in areas that form the higher delta areas, only fine gold can usually be found in these places, and there is not a great opportunity for the concentration of gold here given that there is regular shifting of the channels. In addition, gold does not occur in the parts of the deltas that are underwater. The pot holes and any other low areas in the bed rock of a river or a creek do not usually show that much color as much as they are formed by erosion, and most of the gold that is brought into them by the water current and gravel and sand is usually very ground down and is washed away. In most cases finding gold in a placer occurs from spot to spot. The course metal, which often times comes with some rough or fine gold, can be lying around the bottom anywhere from ten to fifteen feet of gravels, and especially if they have a lot of clay or finer materials in them, however it is usually concentrated at the bedrock or close to it. Also, in the case of a false bottom or clay the streaks can by lying at any height or when it is on any solid material that is not always in the deepest part of the channel. In the case narrow valleys the gold might just be scattered around the whole bottom. In the case of the broader and flatter valleys, the workings that are richer are a lot likely to be thinner than the floor valley and to go along a line that is not the same from the actual flowage. This occurs given that almost all of the gravels with gold in them and that are located in the wider valleys were for the main part built up in the narrower valleys that had moderately high banks. When the slanting started to get reduced, the depression became wider and got buried underneath the deep clay, sand, gravel and the silt. |
