A wildfire charred about 150 acres of grassland and desert tortoise habitat west of Las Vegas on Memorial Day.
The fire, first reported shortly before noon, was just off State Route 160 some 7 miles east of Mountain Springs.
A Bureau of Land Management spokeswoman says the blaze was about 30 percent contained as of Tuesday morning.
Firefighters worked late into Monday evening suppressing the Bird Springs Fire, two miles south of the Late Night Trailhead and State Route 160 in Red Rock Canyon National Conservation Area, BLM spokeswoman Kirsten Cannon said in an email.
“Very minimal smoke is showing from the air and crews on the ground are engaged and finding minimal heat on the fireline,” Cannon wrote. “The fire remains estimated at 150 acres and is now 30 percent contained with full containment anticipated tonight at 8 p.m.”
Firefighters were using handtools, fire engines and single-engine air tankers to drop water on the fire.
No structures are threatened and no roads are closed. No injuries have been reported.
