Narrow Canyons
Give this one a try later!
Fire in a steep narrow canyon can easily spread to fuels on the opposite
side by radiation and spotting. Wind eddies and strong upslope air
movement may be expected at sharp bends in the canyon.
Certain topographic features can influence --- and --- for small areas, independent of
general weather conditions for an area.

The position of the fire in relation to the topography
South and Southwest Slopes
Give this one a try later!
More exposed to sunlight, lighter/sparser fuels, higher temperatures, lower
humidity and lower fuel moisture. These slopes are the most critical in terms
of start and spread of wildland fires.
Creeping Fire
Give this one a try later!
Fire burning with a low flame and spreading slowly.
, North Facing Slopes
Give this one a try later!
More shade, heavier fuels, lower temperatures, higher humidity and higher
fuel moistures. These slopes will have less fire activity than the others.
A fire on ground level is primarily influenced by what 2 things?

Fuels and wind
Elevation
Give this one a try later!
The height of the terrain above mean sea level, usually expressed in feet.
