No serious injuries have been reported, but fire damaged or destroyed 10 homes and five other buildings in the desert ranching hamlet of Moapa (moh-AH'-pah), about 50 miles northeast of Las Vegas.
More than 100 firefighters with aerial tankers and a helicopter are fighting that blaze, which has burned a little more than a square mile of land.
Meanwhile, homes have been evacuated on Mount Charleston, about 40 miles northwest of Las Vegas.
More than 250 firefighters from four states are battling a 20-acre wildfire in steep terrain there. No structures have been damaged.
Both fires broke out Thursday, and officials say they were human-caused.
