Firefighters Protect Homes and Highway 78 as Bald Mtn Fire Grows Near Diamond, Oregon
The Bald Mtn Fire continues to burn in rugged terrain off Dry Creek–McBain Flat Road, east of Big Hill and east of Diamond, impacting Malheur and Harney Counties, Oregon. Fire crews remain engaged in an aggressive suppression effort as the wildfire threatens ranches, cabins, and critical infrastructure along the Highway 78 corridor.
The wildfire has expanded to more than 32,000 acres and remains only 1% contained, highlighting the difficult firefighting conditions created by hot temperatures, dry fuels, and gusty winds.
Firefighters Focus on Structure Protection
Fire personnel are prioritizing the protection of cabins, ranches, and other structures located along Highway 78, including properties near Riddle Road and Manns Lake. Additional bulldozers and firefighting resources have been assigned to strengthen containment lines, particularly along the western edge of the fire.
Officials report that crews are working to establish direct fire lines while maintaining protection for transportation routes and nearby communities.
Challenging Fire Conditions
The Bald Mtn Fire is burning through grass, brush, and rugged rangeland that has been heavily impacted by prolonged heat and dry conditions. Forecasts continue to call for warm temperatures, low humidity, and periods of gusty winds, all of which may contribute to continued fire growth and increased fire behavior.
Residents should remain alert for changing fire conditions, smoke impacts, and any updates regarding evacuation notices or road closures issued by local authorities.
