Ash, Char, and Glass Fiber
                This is from an environmental tapelift collected
                  after the Gatlinburg Fire of 2016. This shows ash
                  (lower and upper left) and a fragment of charred bark (black out of focus). The
                  other major particle is from a yellow glass fiber thermal
                  blanket.
