INCIDENT: Temporary Closure Order Issued for San Gabriel Mountains National Monument, Mt. Baldy 
       
LOCATION: Mt. Baldy
       
SUMMARY: To protect natural resources and provide for public safety, the U.S. Forest Service has issued a temporary closure and prohibition order affecting portions of the San Gabriel Mountains National Monument, including the Mt. Baldy Closure Area.

This Order is effective from December 29, 2025, at 10:00 p.m. until December 31, 2025, at 11:59 p.m.

The Mt. Baldy closure begins at the intersection of Mount Baldy Road and Glendora Ridge Road in Section 30, Township 1 North, Range 8 West, San Bernardino Base and Meridian (SBBM); then continues due west to Section 22, Township 1 North, Range 8 West, SBBM; then continues due north through the summit of Iron Mountain in Section 3, Township 2 North, Range 8 West, SBBM, to Section 27, Township 2 North, Range 8 West, SBBM; then continues due east through the summit of Pine Mountain in Section 30, Township 2 North, Range 8 West, SBBM, to the Angeles National Forest congressional boundary in Section 28, Township 2 North, Range 7 West, SBBM; then continues south along the Angeles National Forest congressional boundary through the summit of Timber Mountain in Section 23, Township 1 North, Range 7 West, SBBM, to Section 27, Township 1 North, Range 8 West, SBBM. 

“The tragic loss of life on Mt. Baldy and repeated rescue responses highlight how dangerous current conditions are, even for experienced hikers. Weather and terrain conditions remain extremely dangerous and unpredictable, posing a significant risk to both the public and Search and Rescue personnel. The temporary closure of Mt. Baldy trails is necessary to prevent additional emergencies and protect lives. The public is urged to respect the closure and avoid the area until it is safe to reopen.” Sheriff Shannon Dicus

Members of the public are required to comply with all posted closure signs and directions from Forest Service personnel. These temporary restrictions are necessary to reduce risk to visitors and to protect sensitive natural and cultural resources. A violation of these prohibitions is punishable by a fine of not more than $5,000 for an individual or $10,000 for an organization, or imprisonment for not more than six months, or both. 

The San Bernardino County Sheriff’s Department advises all subjects to refrain from traveling to or recreating in the Mt. Baldy area for the duration of the closure. Public cooperation is essential to ensure the safety of visitors and rescue personnel and to support ongoing public safety operations.
