BEATTY, Ore. (AP) — A wildfire burning in south central Oregon has destroyed two structures, officials said.

The Herald and News reported Monday that firefighters had made significant progress on the Ponina Fire, which was reported Sunday afternoon. It was burning Monday northeast of Klamath Falls near Beatty.

As of Monday morning, the fire was estimated at 1,400 acres and 10% containment. The fire’s cause is under investigation.

A local Type 3 Incident Management Team took over management of the Ponina Fire Monday.

On Sunday, firefighters were assisted by two air tankers that came up from California, which proved helpful to beating back the blaze. Two local interagency Hotshot Crews started work on the fire Monday and additional resources were on the way.

Area residents, who were told to evacuate as the fire grew Sunday night, were able to return Monday. However, the Klamath County Sheriff’s Office noted people should be prepared to evacuate if conditions change.

Smoke is highly visible in the surrounding area.
