RENO, Nev. (AP) — Authorities in northern Nevada have expanded the evacuation zone where a wildfire has burned about 66 square miles (170 sq. kilometers) of mostly high-desert rangeland north of Reno near Pyramid Lake.

Truckee Meadows Fire Protection District spokesman Adam Mayberry said Monday no structures have been damaged but more than 130 people have left their homes because of the fire that at one point threatened as many as 70 residences.

Only eight spent the night at a Red Cross shelter at the Ironwood Events Center in Palomino Valley north of Reno but more than 300 displaced animals are being housed there, including livestock, horses and pets.

About a 12-mile (19-kilometer) stretch of State Route 446 along Pyramid Lake has been closed in both directions between the Pyramid Highway and Nixon.

The fire was about 15 percent contained Monday afternoon.
