Authorities are asking for help from anyone who may have seen how the Fir Mountain Fire started on August 1.  Kyle Nairns of the Oregon Department of Forestry says their investigation into the fire’s origins is on-going.  He says there were people in the area that evening, and they are hoping that anyone who may have seen anything will let them know.  The Oregon State Police tip line is available for people to report what they observed the evening the fire started.  That number is 800-452-7888.  The containment level for the Fir Mountain Fire was increased to 80% over the weekend as mop-up operations continued, and full containment is expected on Wednesday.
