Welcome to Jefferson County


Jefferson County has something for everyone; from rivers for floating and fishing, to hiking and climbing in the Elkhorn Mountain range, and a large motorized and non-motorized trail system. Boulder, High Ore and Basin are home to several radon health mines, ghost towns, Boulder hot springs and Whitehall hosts Frontier Days every July. The county fair is held in Boulder in August. Jefferson County abounds with natural resources and its economy is based around these, including production agriculture, wood products and mining. Come and visit us!

Air Quality Information

Air Quality information from MT DEQ is available here.


Open burning has been suspended due to the high fire risk. The county has had multiple days of Red Flag weather alerts (conditions favorable to easy ignition and rapid spread of wildfires). Please be careful outside and avoid any activities that may spark a fire. When traveling in the back country it's always a good idea to carry a shovel and a bucket. If you start a fire, even accidentally, you may have to pay for suppression costs so the wallet you save may be your own!
