The Voltaire Fire burning in Carson City is 15 percent contained as of Wednesday morning, with 500 acres burned.

The cause of the fire is officially under investigation, however Carson City Sheriff Ken Furlong said two campers have been detained on allegations they started the fire by burning poop in a hole at their campsite.

The fire is burning sage brush in the Humboldt-Toiyabe National Forest. It is west of the Casino Fandango. Flames are not expected to reach nearby homes, however voluntary evacuations remain for the Voltaire Canyon.
