(Meriam Webster) (Latin, [I]a [U]collection[/U] of washings)[/I] The gold moves to the base of the slope under gravity and water flowing downhill Alluvium - material deposited by rivers. (Britannica) [B](Latin alluvius[/B], from alluere, "to wash against") The gold is concentrated by flowing water in a stream Not a bad idea to check before disagreeing. I have been teaching this and discovering gold mines for more than half a century now. You will find many diagrams on Google that show the difference between the three. [/QUOTE]
