Context & Background
The fire was first reported in the early afternoon of July 31, 2026, near the intersection of Skyline Boulevard and Kings Mountain Road.

The Santa Cruz Mountains region is currently experiencing peak summer dryness, elevating fire danger levels across Northern California.
Cal Fire CZU immediately deployed ground crews, bulldozers, and air support to combat the spread. Multiple air tankers and helicopters are executing targeted retardant drops to establish containment lines and protect nearby properties. The Woodside Fire Protection District has established a command post nearby to coordinate local mutual aid resources.
