Like Chris Kavanaugh said, fire travels UNDER GROUND in roots.

I put out 'smoldering' ground that was 3ft away from the fire PIT. THe fire pit was 1ft tall, and was cleared 4ft to the nearest brush...

The fire was ALMOST to the brush when we put it out, we had to dig down 1ft in the soft soil to put out the fire w/water. Luckily there was a stream about 50ft away so our trips with water bottles was much easier!

Be careful about fires!
