Charred Leaf Fragment

This is from a home impacted by a near approach of the Etiwanda fire. The Etiwanda fire was typical of a Southern California Chaparral fire. These fragments are from the veins of a deciduous leaf. The finely space black bars normal to the long direction of the particles are the reinforcing ribs of the veins. The particle on the left shows a branching structure of the veins in the leaf.
