Incident Overview

Incident Overview

 
The Harris Mountain Fire started on July 23rd approximately 10 miles southeast of Cascade. The lightning caused fire grew quickly, burning over 3,000 acres within the first burn period. Northern Rockies Team 7, a Type II Incident Management Team, assumed command of the fire from the Montana Department of Natural Resources and Conservation (DNRC) at 6:00 AM on July 26th and managed the fire through August 14th.

The fire is located in difficult and rugged terrain with fuels and topography driving fire activity. Location, along with limited resources creates challenges for immediate suppression. Multiple crews, engines, dozers, water tenders and air resources are assigned to the fire and providing point protection near structures.

The Cascade County Sheriff's Office issued evacuation orders and notices for approximately 60 residences from July 25th to August 9th; currently all evacuation orders and notices are rescinded.  No evacuations have been issued for residents in Lewis and Clark County.

Weather Concerns
Recent rains have made some roads inaccessible or necessary to avoid to decrease damage to the roadway due to erosion. Warming trend is expected to continue in the upcoming weeks.
