A pair of persistent islanders tracked down a smoldering fire Monday that had eluded Bainbridge firefighters over the weekend.

The Bainbridge Island Fire Department got an initial call about a possible fire somewhere near Madison Avenue and Monsaas Lane after witnesses said they had seen smoke billowing up from the trees Saturday evening. Neighbors Marshall and Coral Jacobsen called the Bainbridge Island Fire Department at approximately 8 p.m.

Bainbridge Island Fire Department Assistant Chief Jared Moravec said firefighters responded but could not locate any fire.

At approximately 3:45 p.m. Monday, the Jacobsens once again called the department, but this time, they had found the fire firsthand — roughly 300 feet into the forest just north of their home.

“Yesterday we got home and I could still smell it,” Coral Jacobsen said Monday evening.

“I said, ‘We’re going to go find it.’ And we found it.”

“I got a good sniffer,” she added.

Shortly afterward, firefighters from the Bainbridge Island Fire Department and Navy Region Northwest responded, Moravec said.

Five Bainbridge Island Fire Department engines were called to the scene.

By approximately 5 p.m. Monday, the fire, which was estimated at 20-feet across and 30- to 40-feet long, had been 100 percent contained.

The cause was not immediately known.

“It’s under investigation,” Moravec said.
