About 60 firefighters, a helicopter and air tankers from Kamloops and Penticton were attacking a 20-hectare fire south of Merritt today (Monday).
Air tankers were initially deployed late Sunday to the Spius Creek Forest Service Road 42 kilometres southwest of Merritt.
Air crews dropped retardant around the fire as a guard then retired for the night. The next day they were at it again.
"The terrain is a little bit difficult and that's also why the air tankers have been working on it a little bit longer than usual," said Kevin Skrepnek, Kamloops Fire Centre information officer.
"Once the air tankers finish putting that guard down they'll move on the ground and start building some containment lines around it."
The blaze is nowhere near structures, said Skrepnek. The cause is undetermined, but there's currently little evidence of it being human caused.
The fire centre received several calls from Coquihalla Highway drivers noticing smoke on Sunday, but they most likely saw a small fire caused by lightning strike right beside the highway at Juliette Creek, said Skrepnek.
That fire measured less than half a hectare and was quickly extinguished.
