Hundreds of Wyoming residents were forced to flee a wind-driven wildfire that destroyed at least 10 homes even as a separate blaze in neighboring Idaho burned several cabins to the ground and prompted dozens to evacuate, fire managers said on Monday. The fire that broke out on Saturday evening in a brush pile at a landfill north of Wyoming’s second largest city of Casper has charred 10,000 acres (4,000 hectares) of grasslands and trees and led to the evacuation of more than 300 residents, said Bob Fawcett, fire marshal with the Natrona County Fire Protection District.
