when a fire is encircled by a fireline but not under
control
what do prior burns do? slows down the spread of fire
fuel ladder

When is R.H usually lowest mid afternoon
What do narrow canyons preheating, spotting, chimney effect
cause?
narrow canyons where air is funneled and accelerates
chimney effect
the fire faster and upslope
