The Moose Fire was first detected July 17 on the Salmon-Challis National Forest in Lemhi County and is 29% contained as of Sunday, August 14.

SALMON, Idaho — Editor's note: The video above this article was published Aug. 9.

The Moose Fire northwest of Salmon, currently Idaho's largest wildfire, has grown to an estimated 78,084 acres -- more than 122 square miles, an area nearly one-and-a-half times the area of the Boise city limits. However, containment has increased this week, evacuations are being scaled back, and public use is returning to the Salmon River corridor.

Saturday morning, isolated thunderstorms brought rain to the north side of the fire. By the afternoon, cloud coverage had dissipated and temperatures rose to 101° at the Indianola Remote Weather Station.

The weather for the next few days is forecasted to be dry with humidity levels in the low teens, but strong winds are not anticipated.

Smoke may be visible around the Haystack Mountain and Pine Creek areas, as the most active part of the fire is centered around Pine Creek to the ridge above the Salmon Breaks.

Saturday, a new fire was reported near Panther Creek and the Salmon River, but crews dropped 46 buckets and were able to stop the spread of the fire.

Regarding evacuation status, the Lemhi County Sheriff on Friday reduced the evacuation to "READY" status for residents from Tower Creek to North Fork and west to Caddigan Ranch; Squaw Creek to Pine Creek on Salmon Road remains in "SET" status. All other zones are in "READY" status. An evacuation shelter and assistance with placement of pets are available at the Salmon Valley Baptist Church, located at 1230 Cemetery Street.

Vehicles are again allowed to travel unescorted on the Salmon River Road. Pilot car operations have ceased, but may be reinstated as needed if fire situations change.

The main Salmon River is open to rafters and the Spring Creek Boat Launch is open to public use. The Morgan Bar Campground remains closed to public use in order to provide a flight pathway for firefighters working out of a mobile retardant base in the area.

The Moose Fire was first detected July 17 on the Salmon-Challis National Forest in Lemhi County, and was 27% contained as of Saturday, August 13.

After recent rain and somewhat cooler temperatures, firefighters have been working 16-hour days this week to take advantage of the conditions and increase containment.

Structure protection work is ongoing in the Pine Creek Ranch, Panther Creek, Spring Creek, Beaver Creek, Wallace Lake and Highway 93 corridor areas, including Tower Rock, Diamond Subdivision and Jesse Creek. Crews in those areas are assessing structures and surrounding vegetation, and working with property owners to reduce fire threats.

Investigators have determined the Moose Fire was human-caused, but the specific circumstances as to how it started remain under investigation.

The Salmon-Challis National Forest has issued an updated closure order. The Salmon River Road is now open to two-way traffic from North Fork to Spring Creek. Additionally, lands north of Salmon River Road are now open. However, officials ask to the public to drive with extreme caution and to stay out of the fire area north of the Salmon River.

A helicopter accident that occurred the afternoon of July 20 on the Moose Fire is under investigation. Both pilots on board were killed, the Lemhi County County Sheriff's Office confirmed Friday. They were identified as Thomas Hayes, 41, of Post Falls, Idaho, and Jared Bird, 36, of Anchorage, Alaska. 

The sheriff's office said they died after being extricated and taken to medical facilities. An online fundraiser in Hayes's honor has been created to help his father pay for a funeral and to make a donation to the Boise-based Wildland Firefighter Foundation in his memory. An online fundraiser for Bird's family is also underway. GoFundMe has verified both fundraisers.

The Idaho DEQ has issued an air quality advisory with restrictions on outdoor burning for Lemhi County due to particulate matter in wildfire smoke. The forecast is Orange, or unhealthy for sensitive groups, Thursday through Saturday, Aug. 11-13.
