REDMOND, OR -- Firefighters battled an outbuilding fire for more than an hour, Saturday night, west of Terrebonne. As crews responded to NW Grubstake Way at 9 p.m., they learned the building housed large amount of ammunition. Due to the danger posed by the ammunition and the rapid spread of the fire, multiple agencies responded from Bend, Crook County and Cloverdale.

Firefighting efforts were made more difficult by the ammunition and black powder going off inside the building. Crews were forced to temporarily seek shelter to allow the ammunition to burn. 

The outbuilding was deemed a total loss. The cause of the fire is under investigation.
