A juvenile has been charged with starting a wildfire that has burned 60 square miles in northern Colorado and southern Wyoming.

Colorado prosecutors announced the arson charges Friday but didn't release any details, including the suspect's name and age or how the fire started.

The Beaver Creek Fire was discovered on June 19 about 24 miles north of Walden, Colorado. It is at least 75 percent contained but is still active.

Authorities say the fire has destroyed one home and 16 other structures.
