Four Fires Erupt Across Southern Idaho on Memorial Day Weekend, Scorching Thousands of Acres

Southern Idaho firefighters faced a busy Memorial Day weekend as four separate large-acre wildfires ignited simultaneously across the region, collectively burning more than 7,700 acres and stretching resources across multiple BLM and Forest Service districts.

Kinyon Springs Fire

The largest of the four fires, the Kinyon Springs Fire, ignited Monday afternoon around 2:00 p.m. approximately 15 miles southeast of Glenns Ferry in the Twin Falls BLM District. The fire quickly grew to an estimated 3,000 acres on Tuesday before burning an additional 1,573 acres on Wednesday as afternoon winds picked up. By Wednesday evening, fire crews reported that forward progress had been stopped, though the fire remained uncontained. The Kinyon Springs Fire is currently listed on the National Interagency Fire Center (NIFC) as one of two active large fires in Idaho.

Summit Creek Fire

The Summit Creek Fire broke out Monday around 2:00 p.m. approximately 11 miles southeast of Oakley, burning predominantly in timber terrain within the Sawtooth National Forest. The fire reached an estimated 550 acres as of the latest NIFC report and is 0% contained. Fire managers deployed aerial resources including air tankers and helicopters to support suppression efforts, given the fire's location in heavier timber fuels that pose increased resistance to control.

Dewoff Fire and Black Ridge Fire

Two additional fires rounded out the weekend's activity. The Dewoff Fire, located 28 miles northeast of Burley, ignited Monday evening around 6:30 p.m. and quickly burned through an estimated 2,000 acres of grass and brush before crews were able to make significant progress overnight as winds eased. The Black Ridge Fire erupted around 4:00 p.m. Monday, located 8 miles northeast of Richfield, reaching an estimated 1,500 acres. Firefighters reported seven to eight active fire fingers moving through and around lava blisters, creating complex suppression challenges. A smaller incident, the Big Draw Fire near Glenns Ferry, burned approximately 10 acres before crews were able to prevent further spread.

Bled Fire Fully Contained

In more positive news, the Bled Fire, which had burned approximately 395 acres six miles west of Hammett in the Boise BLM District, reached 100% containment, providing crews with a measure of relief amid the otherwise demanding weekend.

Conditions Driving Early Activity

The burst of fire activity over Memorial Day weekend is consistent with warnings fire managers have been issuing throughout the spring. A drier-than-average winter and early warm temperatures have cured fine fuels ahead of schedule across southern Idaho's grasslands and sagebrush steppe ecosystems. With more than 5,000 firefighting personnel currently assigned to incidents nationwide, competition for resources could intensify if additional fires continue to develop at a similar pace heading into June and July, traditionally Idaho's most active fire months.
