ISABELLA, MN -- The Greenwood Fire has burned more than 26,000 acres since it started nearly a month ago.
Portions of the Superior National Forest are now severely damaged after the Greenwood Fire swept through.
Fire Behavior Analyst Trainee Patrick Johnson said the burned land, located on County Highway 2, was damaged on August 23 when the fire made its largest single-day run and doubled in size.
"That day it was also pretty hot, dry, and windy, and those factors combined together make for some really extreme fire behavior," Johnson said.
The former-recreational area made of many trails will be closed for the next several months.
Rick Davis is an incident meteorologist for the National Weather Service who has been collaborating with fire officials to keep them informed on the weather.
Davis said the biggest safety concern right now is falling trees.
"Because of the fire that's burned the duff around the roots, they're very shallow-rooted and we call 'fire weakened trees,' and so any winds of even 20 to 30 miles per hour if it's really a weakened tree can come down," Davis said.
It's not just the wind making the trees fall, the heat from the fire is still smoldering inches beneath the surface.
"This is going to be something that continues to happen for the next month or two, and the trees are going to come down, and it's just going to keep on consuming that organic material," Johnson said.
Davis said not all areas impacted by the wildfire burned this severely.
"We call it a mosaic: some is very low severity burn, some hasn't burned at all, and then some is high severity," he said. "It's a mosaic or patchwork of burn so the entire area doesn't look just like this."
The good news: Davis said more containment is likely with the fall season.
"We're having more cold fronts come through more frequently, and that just helps with the cooler temperatures and the higher relative humilities, that definitely helps with fire suppression," he said.
The goal for fire officials right now is to suppress the fire, mop up what is already burned, and let new life take its place.
Officials said the fire in that area burned around 800 degrees on the day it made its big run.
No one was hurt during its spread.
However, 14 structures are destroyed.
