BELLA VISTA (AP) — Firefighters battling a seemingly constant string of wildfires in California were tackling a new blaze Thursday in the northern part of the state that threatened more than 100 homes.

A fire burning in Yosemite National Park, meanwhile, appeared to be coming under control, with park officials announcing that firefighters had the blaze spanning 7 ½ square miles of backcountry 23 percent contained.

Park spokeswoman Kari Cobb said Thursday that the cables guiding hikers to the top of the iconic Half Dome rock are expected to be open again Saturday for day use. The trail was one of many in Yosemite shut down after a wildfire burning since mid-July flared up Sunday with windy weather.

Many trails and overnight camping in areas near the fire remain closed, but Cobb said the park’s main entrances and many attractions have stayed open.

The fast-moving wildfire in Northern California was threatening 107 homes about 15 miles northeast of Redding in Shasta County. Some homes were under mandatory evacuation orders, state fire officials reported.

The fire had burned through nearly 2 square miles of grass, brush and oak timber as of Thursday morning, a day after it began. It was 15 percent contained.

The blaze, which began as a vehicle fire, was fueled by dry, gusty winds and 100-degree temperatures. Crews expecting the same conditions Thursday called in hundreds of additional firefighters to battle the blaze.
