A drought-driven wildfire in northern New Mexico exploded into a "megafire" of 100,000 acres, or 157 square miles, on Saturday and could still more than double in size, a fire official said, Reuters reported.

Fueled by ferocious spring winds in parched mountain forests, the Calf Canyon fire is by far the largest and most destructive currently burning in the United States.
Around 30 miles (48 km) east of Santa Fe, the fire has destroyed hundreds of properties, triggered thousands of evacuations, and on Saturday burned within a few miles of the city of Las Vegas, New Mexico.
The blaze grew about 50% in 24 hours as a giant column of flame collapsed on Friday night, raining embers and starting new fires.  
Firefighters believe the US West faces a grim fire year, with US Department of Agriculture data showing 80% of the area in severe drought.
