What is now described as two fires about four miles west of Parkdale have burned an estimated 85 acres, and have been 35 percent lined and ten percent contained.  The 1620 Road Fire was reported Monday morning burning in brush, slash, and young timber on private land.  Oregon Department of Forestry spokesperson Christie Shaw says a spot fire was detected Monday afternoon burning in a draw to the east of the main fire in dense vegetation and less accessible terrain.  No structures are threatened.  Overnight firefighters worked to complete line around the original fire perimeter using dozers and existing roads, with handline construction around the larger spot fire continuing today.  A Type 3 management team is taking command of the fire to provide additional support to firefighters and resources.  Aerial resources available to support ground operations today include two fireboss scooper planes, two heavy air tankers, a Type 2 helicopter, and a Type 1 helicopter.  The cause of the fire is still under investigation.
