The fire sparked just after 6:30 p.m. in the near triple-digit temperatures and bone-dry brush.
The blaze scorched at least 35 acres as of Sunday night, and officials say it has the potential to grow. It is zero percent contained.
No evacuations have been ordered, and Highway 2 is shut down from Highway 138 to the Sheep Creek area, according to the San Bernardino County Fire Department.

The cause of the fire is under investigation.
