Box Canyon

Defensive Attack
A calculated attack on part of a problem or situation in an effort to hold ground until sufficient resources are available to convert to an offensive form of attack.

Exposure Fire
Any combustible item threatened by something burning nearby that has caught on fire.
Fire Intensity
A measurement of BTUs produced by a fire. Sometimes measures in flame length in the wildland environment.

Stairwell
An enclosed stairway attached to the side of a high-rise building or in the center core of the same.
Steepness of Slope
The degree of incline or vertical rise to a given piece of land.
