Although this primarily affects ATV users, there are some trails in the area that are approved for 4x4s so you may want to take a look at this EA!
The EA for this project has been released with comments due not later than April 20, 2012.
This project involves the area around and north of the Middle Fork Calispell ATV Trails. It will close these trails during the project period excepting three-day weekends. If you recreate on these trails, now is the time to review the EA and respond by the deadline!
