Im from pa and yes...did my own experiments on it. Melted it with a bic lighter. Large black chuncks burn off and fell to the table. More then half of the volume of the compacted snow melted before any water dripped down off of it. Also, I melted the snow into a clean glass jar and let most of the heavier particals settle out then I poured all of the remaining water out other then a few drops. I took a plasic pipette and swished the remaining liquid around to get whatever the white film that had gathered in the bottom back dissolved into the water. Took one of my pirex dished and poured this solution into it and baked off the remaining water. When the pyrex dish was completely dry I pulled it out to see what was left behind. There was a fine dark material left so I scraped it out with a razor blade and placed the material I gathered on a white piece of paper to observe it more closely. It was a sliverish gray hard material. Looked like soil and had flakes of material that looked like very fine metallic flakes. Im going to do this same experiment with rain after seeing trails and see what I get. And make a youtube video this time.
