DOUGLAS COUNTY, Nev. (KOLO) - UPDATE JULY 13: Investigators have determined the Numbers Fire that broke out near the Pine View Estates area south of Gardnerville was likely caused by a truck’s failing exhaust system.

The fire broke out Monday, July 6, 2020 just before 7 p.m. During the investigation, several fires were located along Highway 395 that are believed to be related to the Numbers Fire.

Investigators with the East Fork Fire Protection District, the Douglas County Sheriff’s Office, the Bureau of Land Management, and the US Forest Service gathered physical evidence indicating that a semi-tractor trailer truck, heading southbound on Highway 395, most likely experienced a failure in its exhaust system. Officials said this possible failure led to hot particles being discharged along the highway right-of-way, igniting dry grass and brush.

Anyone who may have additional information about a semi-tractor trailer truck seen on Highway 395 heading south at around 6:45 p.m. on July 6, 2020, in the area of the Numbers Fire, is asked to send an e-mail to

The Numbers Fire has burned 18,340 acres and is 98% contained.

UPDATE JULY 12 9:05 A.M. Fire officials reported the Numbers Fire in Douglas County is 88 percent contained.

The fire is 18,342 acres or 28.7 square miles.

The smoke on the fire Saturday was from the fire burning interior islands of unburned vegetation inside the existing fire line.

Officials report 6,545 acres are on Bureau of Land Management land, 5,833 acres are on Bureau of Indian Affairs land, and 5,964 acres are on private land.

There is significant fire danger in the area through Monday due to high temperatures, low humidity and wind gusts that could reach 40 mph on the ridges.

Fire vehicles and heavy equipment will be in the area for several days.

Fire management will revert from a federal team to local management on Wednesday.

There is no reported cause of the fire.

The fire burned three homes and 37 outbuildings like sheds, garages or barns.

UPDATE JULY 11, 9:15 A.M. The Numbers Fire in Douglas County remained at 18,300 acres Saturday morning and 40 percent contained.

Higher winds are expected Saturday with gusts reaching 30 mph near the fire. The National Weather Service has a fire weather watch in place, mostly for Sunday and Monday, according to a Numbers Fire update. Conditions remain hot and dry. That increases fire potential from existing embers and makes new fires more likely.

Because the Numbers Fire is burning in steep terrain, air attacks are important to the fire and helicopters are used to transport food and supplies for firefighters. People who fly drones or model airplanes in the area disrupt this help.

There will be increased traffic in the area, especially in the morning and evening.
