Air Dropped Fire Retardant Through the Microscope

Air Dropped Fire Retardant and Paint Spheres

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. When only transmitted light is used the paint spheres cannot be distinguised from the spheres of fire retardant. This is from an environmental tapelift collected in the attic of this home.
