CLARK COUNTY, Nev. (KLAS) — Fire crews are making good progress on the Sandy Valley Fire that sparked last week between Las Vegas and Pahrump.

It has burned an estimated 1,380 acres, revised down from earlier estimates of 1,599 acres. The fire is on Mount Potosi, near SR 160, about 20 miles west of Las Vegas.

The BLM says containment is at 94%, as of 2:30 p.m. Tuesday. Authorities expect full containment by June 17.

Kirsten Cannon from Bureau of Land Management says law enforcement determined the fire was caused when a bullet hit a rock in dry vegetation.

She says there are target shooting restrictions.

“Steel core ammunition is not allowed on BLM nor are explosive targets, near the fight where the fire was started, Tannerite, which is an explosive target, was found,” said Cannon. “I think the most important message is that it’s hot and dry outside and that the fuels, the vegetation out on public lands are very dry. So, we encourage people that use public lands to use them responsibly.”

The call originally came out at 1:30 p.m. Thursday.

Just after 6 p.m., officials said the wildfire had grown to an estimated 300 acres.

By 8:30 p.m., the Bureau of Land Management said in a tweet that the Sandy Valley Fire had grown to 700 acres.

Later, by 10:30 p.m. the fire had grown to 1,500 acres in size, according to the Nevada Fire Info website.

CCFD officials say the fire has extended into trees, creating a large volume of smoke.

No structures have been threatened and no injuries have been reported.

As a precaution, campers and a Boy Scout troop were evacuated from the area.

The Bureau of Land Management, U.S. Forest Service and local fire departments are all working together to battle the blaze.

On Saturday, about 200 firefighters were working to control the fire.
