Firefighters on the Angeles National Forest are using prescribed fire on the Clear Creek fuel break north of Los Angeles that separates the Arroyo Seco from the Big Tujunga drainages.
“It helps to protect some of the largest communication sites anywhere, some of LA’s drinking water storage, and major communities,” said Robert Garcia, Fire Chief on the Angeles National Forest. “It is also on some of the toughest ground we have on the ANF making initial attack very difficult. The adjacent slopes are unfortunately known from such incidents as Woodwardia, Bryant and more recently the origins of the 2009 Station Fire.”
When I worked on the Laguna and El Cariso Hotshots nearby on the Cleveland NF, to us the ANF was infamous for its extremely steep slopes, which are evident in these photos.
In most other locations super-steep slopes are not a serious obstacle while conducting prescribed fires, as in the example below.
