Brown Snow
Year or two ago we had a snow that was slightly brown. When it melted, everything was covered in a fine layer of dust, especially noticable on cars. I had a tarp outside that was covered in this snow and was able to wash this dust off of it into a bucket, which I then let evaporate, resulting in several grams of this fine grained material. Turns out the source of the dust was dust storms in China. Perhaps I should sneak that sample in with our next shipment of core samples to the lab, get a 40 element package on it and see what is in there. Then I could get on the local news and claim it was from chem trails.
(Hoard those silver bullets, TB, have you been seen the price of silver lately?)
