The wildfire burning near Harrison Hot Springs has grown over 10 times in size since it was discovered over the August long weekend.
Officials were first alerted to the fire by Wood Lake on Sunday, and initially estimated it to be about 45 hectares in size.
By Tuesday, it had grown to 600 hectares, according to the BC Wildfire Service.
The fire isn't threatening any homes or structures, but RCMP said several nearby campsites, including one at Wood Lake, are still under an evacuation order.
Wind is fanning the aggressive fire, blowing smoke and embers, making it tough for fire crews to do their job, officials added. Provincial fire information officer Kevin Skrepnek said it's hard to measure just how big the blaze has gotten.
"[It's] creating so much smoke, it's quite difficult to ascertain an accurate size at this point, just because of the wind and the conditions in the area.''
Air tankers, including the famed Martin Mars bomber, were called in to help fight the flames on Sunday.
According to the wildfire service, the blaze was human-caused and "entirely preventable."
So far this season, nearly $170 million has been spent fighting wildfires in B.C.
