BEND, Ore. - Evacuations prompted by the Two Bulls Fire have eased just as efforts to find the person or people responsible ratcheted up.
The 6,908 acre fire is now 55 percent contained. Fire managers don't expect the burn area to grow.
The army of firefighters laying siege to the blaze is down to 638. More than 1,100 people were working the fire earlier this week.
Since Saturday, fire suppression has cost an estimated $4.3 million, according to fire managers.
The Skyliners Road area outside of the City of Bend is now at Level I evacuation, the lowest level of notice. Fifty homes in the area were under Level III evacuations as the fire rages out of control earlier this week.
All other evacuation notices were lifted as of Thursday morning, the Deschutes County Sheriff's Office said.
Reward increased to $31,500
Investigators continue to search for the cause of the fire, which may have been intentionally set, the sheriff said.
"The fires are suspicious in nature and the ongoing investigation indicates suspicion of potential arson," Sheriff Larry Blanton said.
The reward for information leading to an arrest and conviction of the person or people responsible more than doubled in the last day to $31,500.
Most of Phil's Trail mountain bike area has reopened, but there are still US Forest Service Road Closures in place.
The Two Bulls Blog has current information on these closures.
