(CNN) — Firefighters near Yosemite National Park made gains Saturday afternoon on a wildfire that torched 300 acres, injured one person and forced the evacuation of some nearby homes.
More than 745 fire personnel contained 25% of the wildfire, which ignited Friday, California Department of Forestry and Fire Protection said Saturday.
Mariposa County Sheriff’s Office evacuated an undisclosed number of residents in the Ponderosa Basin area, and authorities said 700 structures were threatened.
California’s ongoing historic drought is helping fuel the flames in the park’s so-called Bridge Fire, authorities said.
“Fire burning at a moderate rate of spread. There continues to be a threat to the Ponderosa Basin community,” Cal Fire said. “Access to the fire is difficult due to steep terrain.
“Firefighters are experiencing extreme fire behavior conditions due to drought and low fuel moisture,” the agency said.
No details were immediately available on the injury and evacuations.
An evacuation shelter was set up in the New Life Christian Fellowship in the community of Bootjack, authorities said.
