The Bean Canyon fire started with a bolt of lightning.

In less than two days, it's grown to 3,700 acres.

"They're going to have about 100 people- both local, state and federal" said Gallatin County Sheriff Brian Gootkin. "They've got three helicopters and three tankers working it right now."

Flames are burning through state and private ranch land, but no structures are threatened.

Sheriff Gootkin said fire crews are working to keep it that way- especially because there are homes over the ridge.

"There's obviously some concerns with the wind possibly heading over to the Maudlow area" he said. "That's what everyone is working on, to try and stop it right in this rough terrain and keep it where it's at."

Tankers spent the day dropping retardant near the fire lines, to slow the flames down.

From there, ground crews came in and used their resources to smother the blaze where they could.

On Tuesday evening, hot shot crews had just come in and were headed toward the flames.

"We'll do whatever we need to do" Sheriff Gootkin said. "This is a team effort- it's the fire folks, it's us, it's local, state and federal. And we really work well together."

He said several counties and agencies are doing what they can on the sidelines, so everything runs smoothly on the fire line.

"All's we're doing is providing the command post, and whatever they need form our office" Gootkin said, adding "they're praying for rain just like everyone else."

He said fire crews will come up with a plan of action Wednesday morning, after they assess their progress from Tuesday night.

A Type 3 Organization is managing the fire. Current resources assigned to the fire include:

8 Engines
2 Dozers
1 Skidgine
6 Tenders
3 Helicopters
3 Fixed Wing Aircraft
