Thanks, I think they were on the Gulf side. The guy ended up being an oil geologist eventually. And later a college professor, teaching "Rocks for Jocks" with a rock hammer in one hand and a fishing rod in the other. Had a summer place up near Atlin, BC. I've got a nice picture of him at the hot spring south of there. A very pretty meadow, with the spring in the center and a little watercress-lined stream flowing away.

The reason for the concentration is, (trust me on this) is that the point source crosses the river. Otherwise, if you follow the distal school of reconcentration, there would be gold in every fast river in the Rockies. We are running by actual test (mine), in gold areas, about 1 river in 20. Most popular vein sources are lead-zinc veins. So why don't you see much galena or silver in pans? It breaks down extremely fast. Gold concentrates where the river is relatively faster. For any certain size of gold, "traps" or concentrations occur where the creek is below a certain absolute speed. It also may require a standing wave effect not to "trap" gold, but to wash away the diluting light sands and leave the gold. This is why fast braided streams with boulders and waterfalls in them yield colour. The rotary wave action behind an obstruction lifts the quartz and puts it back into the river stream but does not lift the gold, as it is too heavy. In order to find gold, think vein sources, volcanics, gabbros, or granite mantos necessary to do this, fast rivers running through the volcanics or granite caps, and washing effect, within from 100 feet to 1 to 2 miles (up the mountain) of source, not transport effect. Transport is very limited. Washing is predominant. Locally washing will be evident if the detritus rocks are slaty blue-brown volcanics with clay and magnetite in the stream bed by eye or magnet test. Why magnetite? It is a heavy remainder mineral indicating concetration or richness. That is why buried dry placers are best prospected for with a magnetometer. EC<:-}

marcos, Here comes another newbie question... What is the meaning of the word "placer" in miner terms? At first I thought it was only the name of a gold company. Now after reading the past posts it appears to be the name of an activity. I looked in the dictionary and only found the following... Main Entry: plac·er Pronunciation: 'plA-s&r Function: noun Date: 1579 : one that places : as a : one that deposits or arranges b : one of the winners in a competition
