Parts of a Fire
Head(Front) Bays / Fingers Flanks (parallel time main direction of spread) Back (base, rear) Islands (unburned fuel) Spot Fires (patches outside main fire)
Six Fuel Factors
Moisture content - single most important Fuel Condition - living vs dead Size Class - fine, medium, heavy Quantity - fuel load Arrangement - Horizontal and vertical distribution Continuity

4 Weather Elements Effecting Fire
Wind
Percipitation
Relative Humidity
Temperature
Topography Aspects
Slope - burn uphill faster
Aspect - influences amount of solar radiation (hills, south facing)
Elevation - wind speed, temp, humidity
Shape of Country - wind speed
