RENO, Nev. (AP) - The U.S. Bureau of Land Management says four separate wildfires that broke out in north-central Nevada this week all were caused by humans.
The fires that began on Tuesday near Interstate 80 between Lovelock and Winnemucca are all now either out or under control.
The largest, the Union Fire, reported Tuesday south of Mill City about 130 miles (209 kilometers) northeast of Reno burned about 2 square miles (5 sq. kilometers) before fire crews controlled it Wednesday.
No one was hurt but two structures and an RV were destroyed.
Three other fires reported Tuesday and Wednesday in the same vicinity burned between 1 acre (0.4 hectare) and 237 acres (96 hectares).
No structures were damaged.
The BLM said Friday the causes of all four are believed to be human-related and are being investigated by the state fire marshal.
