As I haven't yet done an extensive internet search on all American states in which gold can be found, I had no idea that Indiana is one of those states.
[After giving this some thought and listening to the video, I realized that I was thinking about Indiana's lack of igneous and metamorphic rocks. I had forgotten about Indiana's glacial till. Silly me! There are also scattered diamonds in the glacial till of Indiana and other states with surficial glacial till deposits. So if panning or sluicing in Indiana, check your heavy mineral concentrate for diamonds, too. The diamonds are presumably from unknown Canadian source rocks.]
[Just a reminder: Before you take any sort of power dredge or sluicing system out into a creek, please check for any State or Federal restrictions on their use. To be honest, their overuse can be disruptive to creek or river ecosystems as the larval stages of numerous aquatic invertebrates may be buried in the shallow sand of the bottom sediments. And if it happens to be locally restricted or banned, your equipment may be confiscated.]
