PASO ROBLES, Calif. - Calls started coming in after 3:00 pm Tuesday afternoon of fires burning in dry brush along Highway 101 in northern San Luis Obispo County.
There were a total of five spot fires that were responded to by several agencies between Atascadero and San Miguel.
"The very furthest south fire was discovered just north of San Anselmo Drive (in Atascadero)", says Cal Fire spokesperson Chris Elms, "the very northern one was right along Exline Road in the San Miguel area."
The largest of the spot fires was just north of the north Spring Street off ramp where it spread quickly to 12 acres and forced the closure of the northbound Hwy 101 off ramp for several hours.
The south Spring Street northbound off ramp was also forced to close as firefighters doused flames and put out smoldering hot spots.
What caused the string of fires so close to Highway 101 is under investigation.
"We received reports that there was a vehicle in the area dragging a chain, we have not confirmed that", Elms says, "we do have investigators on scene working to confirm that situation."
The sport fires were fed by extremely dry grasses that grow all along Highway 101.
"This grass is just a fuse right now, its ready to burn, its extremely dry", Elms says, "were just asking people to please be careful."
