In Pictures: Huge Nevada Wildfire Turns Las Vegas Sky Red
The fire started as a 10-acre (four hectares; 0.04 sq km) brush fire on Sunday afternoon.
By the early evening local parks officials said it had engulfed about 5,000 acres (20 sq km).
Crews hope the winds will drop off on Monday so they can travel to the area.
The American Red Cross of Nevada has opened an evacuation centre in a local primary school for residents of Mount Charleston.
It is not known what caused the fire, but some reports are suggesting multiple fireworks in the area may have started the fire.
