Wildfires - Nevada, USA

The Martin fire started July 5 near Paradise Valley, Nevada. In the days following, it spread to 399,429 acres, according to the incident information system on Monday. Grass, brush and some small pieces of timber fueled the fire, spreading it across the county. There was also a persistent wind that helped grow the fire from where it was already burning.

The fire, burning in Humboldt County, was the largest burning anywhere in the entire country, according to NASA. The space agency captured the fire and the residual smoke on one of its satellites. The flames were reaching heights of 45 feet, and the fire was spreading quickly. The cause of the fire remains unknown.
