Many kinds of heavy equipment are used on the fire line to clear the area of consumable fuel. By removing trees and brush to mineral soil, they create “fuel breaks” that reduce the fire’s spread.
In this photo, a bulldozer works to scrape vegetation off the surface of the ground. Hand crews may work ahead of dozer operations as “boots on the ground” to cut trees and brush within the dozer’s path.
As of August 26th, there have been approximately 8 miles of bulldozer line put in along the south and west sides of the fire area.
