2. Ponderosa Pine Bark Ash
4. Scrub Oak Leaf Ash
5. Russian Thistle (Tumbleweed) Ash
6. Fountain Grass Ash
7. Cheat Grass Ash
8. Sugarcane Leaf Ash

1. Soot from a Wooden Match: Soot is an agglomerate of carbon-based particles. This sample shows patterns of agglomeration from a combustion source that generates gas-phase fuel directly from the solid phase in response to heat.
2. Ponderosa Pine Bark Ash: Thermally modified calcium oxalate prisms with aspect ratios, Length/Width, of greater than three are common in smoke from pine forest fires.
3. Douglas Fir Bark Ash: Thermally modified calcium oxalate squares and rectangles with aspect ratios, Length/Width, near one are common in smoke from forest fires of Douglas fir, spruce, hemlock, and true fir forests.
4. Scrub Oak Leaf Ash: Thermally modified calcium oxalate trapezoidal twins and complex prisms are common in smoke from oak containing chaparrals and oak-grassland fires. These are common in central and southern California, northern Mexico, and in similar environments worldwide.
5. Russian Thistle (Tumbleweed) Ash: Russian Thistle, Salsola tragus, is a common plant in arid grasslands from Texas to North Dakota and the Inland Basin from California to Washington State.
6. Fountain Grass Ash: This is a common invasive grass in arid environments subject to grassland fires. Characteristic silica phytoliths are common in smoke from these fires.
7. Cheat Grass Ash: This is a common invasive grass in arid environments subject to grassland fires. Characteristic silica phytoliths are common in smoke from these fires.
8. Sugarcane Leaf Ash: Sugarcane is a tropical grass grown agriculturally in the southeastern United States and Hawaii and in many other tropical environments worldwide. It is typically subject to a controlled burn prior to harvest. Smoke from these fires typically contain silica phytoliths and char from the leaves of sugarcane.
9. Exterior Windowsill, No Fire: This is an example of exterior particles common to Western Washington in the late summer. The closest wildfire is over one hundred miles away on the other side of the Cascade Mountain Range.
10. Exterior Surface of an Automobile: This is an example of exterior particles common to Western Washington in the late summer on vehicles often driven at highway speeds. The closest wildfire is over one hundred miles away on the other side of the Cascade Mountain Range.
