Image 3: Relief
This portion of the DEM from the fire area has been inverted, so that the lower elevations are brighter, and the ridgetops are darker.
This depiction correlates with the expected fuel loading- heavy vegetation on the lower slopes, heaviest in the riparian areas, and sparse on upper slopes and ridgetops.
Open both Image 2 and Image 3, then tab between them to perform a visual survey of the correlation between relative elevation and residual heat, where elevation is a proxy for fuel load. |

Image 4: Thermal
The same area as in the inverted DEM above, showing the thermal in grayscale.
The bright pixels interior to the fire indicate residual burning and/or lingering heat from intense combustion- a result of higher fuel loading in those areas.
Open both Image 3 and Image 4, then tab between them to perform a visual survey of the correlation between relative elevation and residual heat, where elevation is a proxy for fuel load. |

Image 5: NAPP photo
The same area as in the thermal above; the vegetation appears red in this Color IR photo from Sept. 30, 1996.
It is evident that the north-facing slopes (darker areas) support more vegetation than the south-facing slopes (lighter areas) and that most vegetation is found in the stream bottoms.

Open both Image 7 and Image 8, then tab between them to perform a visual survey of the correlation between terrain aspect and residual heat, where aspect is a proxy for fuel load.

Image 9: Relief & Thermal
The inset charts show the pixel values along the transect line, starting at the north end. Both charts depict 3 small ridges (actually gullies), then 2 larger ones. The asymmetry in the thermal may be due to higher fuel loads on the north slopes. |
