Crews were on the scene of a vegetation fire on Skinner Butte in Eugene Monday.
Smoke from the fire was visible in the downtown area during the afternoon as the fire worked its way uphill, burning about two acres before being brought under control.
A wireless alert sent to cell phone users in the area said people "on the butte" should evacuate.
KLCC confirmed with Eugene Springfield Fire that forward progress has been stopped, and there are no current structural threats.
“Any place that is allowed to grow somewhat naturally with those lighter grassy fuels that stand up, they catch fire really easily," said ESFD Chief Mike Caven. "And that’s part of the challenge in a natural area like that, the ability for fires to catch and spread.”
Caven said various factors allowed the fire to be stopped quickly including a response time of around five minutes, the removal of low-hanging tree branches by the city in recent years and favorable weather.
“It’s overcast, cool, the humidity is up," he said. "That gave us a chance without any significant potential fire spread or embers being cast and starting new fires in the neighborhood or on the other side of the butte.”
Crews are expected to remain on the scene through the afternoon to make sure the fire is fully extinguished.
