A fire driven by strong winds burned through 600 acres of the Santa Cruz Mountains this morning, burning two buildings, threatening 85 others and forcing evacuations.

Roughly 80 to 100 people were told to leave their homes in the area of Maymens Flat Road, Highland Way and Ormsby Cutoff. No injuries had been reported by mid-day, but two outbuildings and one trailer had been destroyed.

First reported around 3 a.m., the so-called Loma Fire started near Maymens Flat Road, close to the area that burned in the Summit Fire of 2008.

By late this morning, 937 firefighters were attacking the blaze, using 100 fire engines, eight air tankers and five helicopters, among other resources. But the fire remained completely uncontained.

The Summit Fire, which started in May 2008, burned more than 4,000 acres, injured 12 people and destroyed 132 homes and outbuildings, state fire officials said.

Authorities said a man accidentally set the blaze as he cleared brush for a landowner. He was charged with one felony count of unlawfully causing the fire.
