Never Ending Ash and Soot

When we got our first snow we mistakenly thought that we would be done with the wildfire ash and soot for a while. We were wrong as when the winter winds blew it blew ash and soot off the dead burned trees and the above photo shows what our snow looks like after a couple days of strong mountain wind.
It reminds me of when I was a child and we would drive down from south central Michigan to Aurora, Illinois which was just west of Chicago. The trip in the winter would take us through Gary, Indiana which had a lot of steel plants, smelting operations, and factories. I used to think the snow that was red, yellow, orange and grey looked pretty cool without realizing what was causing it. Now our snow is grey and black speckled and I miss the pure white snow we used to have.
