Part 2 of the Indiana Gold video.
Initially, while beginning Part 1 of this video series, I was surprised that Indiana had gold, as Indiana lacks any discovered, exposed igneous or metamorphic rocks.
After giving this some thought and listening to more of Part 1 of this video series, I realized that I had forgotten about Indiana's glacial till. Silly me! This is reworked glacial till.
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 and gravel of the bottom sediments. And if it happens to be locally restricted or banned, your equipment may be confiscated.]
