A huge wildfire near Yosemite National Park in California continued to threaten San Franciscos water supply Monday,while officials warned that the blaze was so hot that it could send sparks into new,untouched areas.
Officials reported some progress as Stanislaus National Forest spokesman Jerry Snyder said containment of fire was at 15 per cent Monday morning,up from 7 per cent the previous night. He said crews were helped by cooler temperatures caused at least in part by the shadow by the plume of smoke.
The fire continued to grow,however,and was 606 sq kilometers in size covering more ground than the city of Chicago.
The fire,burning near one of the countrys most popular national parks,edged within a mile of the source of San Franciscos drinking water.
The fire is now one of the biggest in California history.
