According to a fire update Sunday, the Swan Lake fire has grown to 25,161 acres with winds pushing the fire toward the east of Mystery Creek Road and southeast of Sterling.
"As the winds shifted throughout the afternoon, a few spot fires occurred over the control lines and were contained by ground resources working with helicopters dropping water," fire managers wrote. "The overall strategy is to slow fire progression on the eastern flank and push it towards the mountains to the east as the fire burns in thick black spruce stands that have not burned since the last wildfire in 1947."
Swan Lake fire managers issued a travel advisory for Sterling Highway, notifying motorists of reduced visibility from smoke and travel delays between milepost 58 and milepost 75.5. Motorists are asked to drive slowly and with headlights on.
