Hello Doug All good thoughts. >> Several adjacent rivers may have the same size because that is the common crystal size in a large batholith the rivers all drain (perhaps anything smaller just goes straight out to sea without ever stopping). << Still should be some dark material that sorted with the sand. >> Cloudier quartz crystals are likely cloudy because they have more flaws than clear ones from the same chemical environment. They are thus more likely to be shattered into powder, leaving only the relatively flawless ones to form sands. << I like this too …but not all off color material would be flawed some could be harder. The dark clays I have looked at have are mostly clear or slight cream single colored but varied in size with a minor portion of colored materials in them. My experience in this is limited but I am none the less shocked by how much of the material even in dark clays is clear. I am wondering how much this is true with other clays. You scoped the clays much? Kamron
