Glossary: what each term means
Minimal

Barely moving. Low, thin smoke.

Smoldering

Burning without flame, in the ground or in roots. Can flare up days later.

Creeping

Moves slowly, hugging the ground.

Moderate

Spreads with low, steady flames.

Active

Spreading evenly and steadily, with visible flame.

Extreme

Fast and unpredictable.

Running

Runs along the ground much faster than a person walks.

Flanking

Grows along the sides, not head-on.

Backing

Moves against the wind or downhill, which makes it slower.

Crowning

Climbs into the treetops and jumps crown to crown. It can't be attacked from the ground.

Short Crown Runs

Climbs into the crowns in bursts and drops back down.

Torching

Whole trees flaring up like torches.

Isolated Torching

Single scattered trees flaring up whole, like torches.

Group Torching

Whole clumps of trees flaring at once.

Spotting

Wind carries embers through the air and starts new fires ahead of the front: that is how a fire jumps a road or a firebreak.

Wind Driven Runs

The wind pushes it in long runs in one direction.

Burning across Mohave County, Arizona, the Mount Emma Fire has reached full containment after a nine-day run that consumed 368 acres of federal land. Managed as a Type 4 Incident by the National Park Service with a 16-person crew, the fire progressed at an approximate average daily growth of 41 acres per day. The incident location is situated 60 miles northwest from the South Rim of the Grand Canyon National Park.

Current fire behavior on the landscape is minimal, characterized by smoldering, backing, and creeping through two-foot brush fuels. The operation incurred a total cost of $1.1 million while utilizing a Type 4 Incident Commander management structure.

This event unfolds during the region's typical fire season, which runs from June to October. Nationally, the broader context shows 3,186,142 hectares burned so far in 2026, tracking 42 percent below the two-decade average.
