Sonora, CA…Seasonal closures of some National Forest System roads and trails that are designated for motor vehicle use pursuant to 36 Code of Federal Regulations (CFR) 212.51 begin on December 15 and will remain in effect through April 14, 2023.

The free Stanislaus National Forest Motor Vehicle Use Map, or MVUM, indicates which National Forest roads and trails are subject to the seasonal closure.  This map may be downloaded by visiting the Stanislaus National Forest Maps webpage at https://www.fs.usda.gov/main/stanislaus/maps-pubs. Free paper copies of the MVUMs are available at one of our Ranger District offices or the Forest Supervisors office.

Please note that if the MVUM identifies a Forest System road or trail as closed, it is closed for the season regardless of whether or not a gate exists or whether or not gates are closed and locked.

National Forest System roads and trails identified in the MVUM as being open year-round may be hazardous due to local weather conditions. Be advised that Forest System roads are not maintained for winter or wet weather use. Use caution and drive defensively when traveling on open roads in the forest through the winter. Rocks, fallen trees, snow and ice may be encountered in the roadway. Visitors are urged to be prepared for a variety of hazards and should recognize that conditions can change quickly during inclement weather.  Wet, saturated roadbeds are easily damaged, which can require costly repairs to roads and adjacent resources.
