A large grass fire in Palo Alto was 100 percent contained by 7:30 p.m. Monday evening, according to Palo Alto police and fire communication manager Charlie Cullen.
The blaze, which burned about 125 acres, was 95 percent contained at 7 p.m. and was fully contained at about 7:30 p.m., Cullen reported.
Cal Fire first received word at 4:13 p.m. Monday of the fire burning in the foothills near Junipero Serra Boulevard and Frenchmans Road between Stanford University and Interstate Highway 280.
Firefighters from the Palo Alto Fire Department and Cal Fire responded to the blaze, which threatened structures in the area of Old Page Mill and Page Mill roads.
The flames prompted a voluntary evacuation of homes in the area, but no structures were damaged and no injuries to residents or firefighters were reported.
Plumes of smoke emanating from the fire could be seen from miles away.
"You can see it from at least 30 miles away," a witness driving on U.S. Highway 101 in Belmont reported. "The entire sky is filled with smoke -- big plumes of gray and white smoke," she said.
While mutual aid firefighters are now being released from the scene, fire investigators are arriving to determine the cause of the blaze,
Cullen reported firefighters will remain at the scene overnight to complete overhaul and check for hot spots.
