Fire officials have determined that humans started the massive wildfire that has burned nearly 700 square miles in a remote area of northern Nevada.
The National Fire Interagency Center confirmed Wednesday the Martin Fire is human-caused.
Investigators say they suspect that Fourth of July campers started the blaze -- that first was reported on July 5 -- near the rural town of Paradise Valley, about 200 miles northeast of Reno. But the specific cause remains under investigation.
The blaze that has charred an area nearly half the size of the state of Rhode Island is now 48 percent contained, with no populated areas currently are threatened.
Federal officials are holding community meetings to update area residents on the status of the fire; the meetings are held at the Humboldt County Commissioner's building in Winnemucca and the Bureau of Land Management district office in Elko.
