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.

The story so far

Burning across federal timber lands in Millard County, Utah, the Widemouth 2 Fire scorched a path about two miles southwest of Kanosh over an 87-day span before finally coming to an end. Driven by timber litter and understory, the natural-cause blaze averaged roughly 1,491 acres of daily growth on its way to a final measured size of 129,742 acres.

By the time response operations concluded under a Type 3 Incident command managed by the USFS, personnel had brought the fire to 98 percent containment, running up a total suppression cost of about $34.5 million. Satellites in the final hours picked up two heat detections within the 48-hour window near the area, where minimal, smoldering, and creeping fire behavior was observed.

This incident unfolded during the region's typical fire season, which runs from June to October. Nationally, the broader context shows 3,442,406 hectares burned so far in 2026, marking a figure that is 37 percent below the two-decade average.
