In ground fire terminology, which term refers to the point where the fire began?

• A. Head
• B. Origin
• C. Finger
• D. Heel

Answer: (B)

The starting point of a ground fire is called the origin. This term marks where ignition actually occurred, and it serves as the reference point for mapping how the fire spread and for understanding the conditions that helped it grow. As a fire advances, the leading edge moves outward from that origin and is typically referred to as the head. Other terms describe features of the burned area during growth—such as narrow extensions that can form from the main front—rather than the place where the fire began. So, when the question asks for the point where the fire began, origin is the precise and standard term.
