Day 2: Big Rock Fire grows to 2,400 acres with zero containment as night falls on Saturday
Published at | Updated atLATEST UPDATE:
As of 11 p.m. Saturday, the Big Rock Fire has doubled in size, and grown to more than 2,400 acres with zero containment. The fire remains extremely fast moving, and erratic, according to latest information from the U.S. Wildland Fire Service.
Fire pressed the containment lines near some houses this afternoon, but no residences were lost. However, two minor structures have been destroyed.
While crews diverted to protect threatened structures, the fire spread both to the southwest towards Cress Creek, and to the northeast, reaching Idaho Endowment lands south of Moody Creek. The fire also spotted east across Little Kelly Canyon and into Kelly Canyon.
Resources were stretched thin by the extreme fire behavior experienced on Saturday afternoon.
Sunday will be another extreme fire weather day. The National Weather Service has issued another Red Flag Warning for gusty winds, high temperatures, and low humidity, which could again result in significant and extreme fire activity and growth.

ORIGINAL STORY
HEISE — The Big Rock Fire near Heise grew to an estimated 1,000 to 1,200 acres on Friday night following hours of active and aggressive fire behavior.
An accurate aerial mapping of the area is still pending as of 9 a.m., and the size of the fire may change.
Eastern Idaho Interagency Fire spokeswoman Juley Smith says that thus far, there does not appear to be any damage to structures. Fire lines have been built along roadways protecting areas, such as Heise Hot Springs and the 7N Ranch Resort. Structures are still considered threatened despite protective measures.

The fire moved in a westwardly direction Friday night, but that could change on Saturday due to extreme fire weather conditions. Ground and aerial crews continue to work on the fire.
