A 64-year-old Montana man is banned from all federal lands for two years after being convicted of building illegal hunting camps and a trail in the Helena National Forest.

U.S. Magistrate Judge Keith Strong found Robert Myers of Jefferson County guilty of four misdemeanor charges including building trails and structures and camping longer than the state limit of 14 days.

Strong fined Myers $1,700 and banned him from all national forests and national parks for four years, but suspended two years after Myers paid the fine.

The Forest Service began investigating Myers' camps in 2010.

Forest Service law enforcement officer Tony Fedele tells the Helena Independent Record the agency is investigating several other illegal camps in the Helena National Forest.
