The wildfire threatening Yosemite National Park grew Tuesday to become California’s seventh biggest ever, as firefighters battled to protect San Francisco’s main water supply.

The so-called Rim Fire now covers some 73,000 hectares — an area bigger than Chicago — and was still only 20 percent contained, albeit up from 15 percent on Monday.

A main road into Yosemite, one of America’s top tourist draws, remains closed as more than 3,700 firefighters battle the flames.
