Unattended campfire caused wildfire near Yosemite; 1,500 evacuated

An unattended campfire near a main route into Yosemite National Park has grown into a more than 2-square-mile blaze that officials said Tuesday has led to the evacuations of 800 homes and 1,500 people. California Department of Forestry and Fire Protection officials released the cause of the fire Tuesday, as 2,200 firefighters - up from more than 700 on Monday - worked to gain the upper hand on it amid windy, dry conditions. No other details were available about where the fire started Sunday, spokeswoman Karen Guillemin said. The fire 6 miles northeast of Mariposa remains 15 percent contained.
