A fire burning in eastern Santa Clara County was spreading on Monday after jumping a containment line.
The Mines Fire began at about 2 p.m. on Sunday in the area of Mines Road and San Antonio Valley road east of Mount Hamilton. The fire had burned at least 132 acres as by 5:23 p.m. Sunday and was 40% contained. Forward progress was reported stopped on Sunday evening.
On Monday afternoon, however, Cal Fire reported what it called a slop-over – when a wildfire crosses over an established control line – with a dangerous rate of spread to the east with structures threatened. The Cal Fire incident command said the slop-over had consumed an additional 40 acres.
#MinesFire [update] Mines Rd X San Antonio Valley Rd, San Antone Valley (Santa Clara County) is now 172 acres. Additional air and ground resources are at scene and responding.
