The fire near Gallinas Canyon is more than 70 percent contained, officials said Monday.
The blaze, which started last Friday night, has burned 777 acres. No evacuations have been ordered.
The first is about 2.5 miles south of Gallinas Canyon, northwest of Las Vegas.
Officials said that for a time, it was the nation’s top priority forest fire because of its nearness to the Gallinas watershed, which supplies 90 percent of Las Vegas’ water.
