Details of the Tragic San Geronimo Valley Accident
The fatal collision occurred around 7:30 p.m. on San Geronimo Valley Road, a winding route connecting the communities of San Geronimo and Forest Knolls. According to reports, the SUV carrying the six teenagers veered off the road and collided with a tree before catching fire.
First responders rushed to the scene to find the vehicle engulfed in flames, with a horrifying situation unfolding before them.
Heroic Rescue Attempts Amid Chaos
When emergency personnel arrived from nearby Fairfax and Woodacre fire stations, they discovered Marley Barclay as the only conscious passenger. Witnesses reported seeing her desperately pounding on the window and screaming for help as the vehicle burned.
Despite the quick response from fire departments across Marin County, including units from San Rafael and Novato, the four other students could not be saved. The tragedy has left first responders from throughout the Ross Valley deeply affected.
The Marin County Sheriff’s Office and California Highway Patrol continue to investigate the circumstances surrounding the crash. Authorities have not yet determined whether factors such as speed, road conditions in the rural West Marin area, or other circumstances contributed to the accident.
Community Grieving Process Begins
On Monday morning, students and staff returned to Archie Williams High School in San Anselmo with heavy hearts. Outside the school building, impromptu memorials featuring flowers, photographs, handwritten notes, and personal mementos began appearing as classmates sought ways to honor their lost friends.
School District Response and Support Services
The Tamalpais Union High School District, which serves communities throughout central and southern Marin including Mill Valley, Corte Madera, and Larkspur, released a statement expressing “profound sorrow” over the tragedy. District officials acknowledged the “immense pain felt throughout the school and district community” and quickly mobilized crisis counseling resources.
“We are devastated by this unimaginable loss,” said a district representative. “Our focus now is supporting our students, staff, and families through this extremely difficult time.”
Grief counselors from throughout Marin County, including specialists from Tiburon, Sausalito, and Kentfield, were made available at the school to help students process their emotions. Additional support services have been established in community centers in Ross and San Anselmo.
Broader Impact Across Marin Communities
The tragedy has resonated far beyond the immediate San Anselmo area. Neighboring schools in Greenbrae, Strawberry, and Belvedere-Tiburon have sent messages of support and solidarity.
Community vigils are being planned across Marin County. The first is scheduled to take place at Creek Park in San Anselmo.
Local youth organizations in Bolinas, Stinson Beach, and Point Reyes Station—communities along the route many West Marin students travel daily—are also creating support networks for affected teenagers.
The accident serves as a heartbreaking reminder of the fragility of life and the importance of road safety throughout Marin’s diverse topography of coastal, valley, and mountainous roads.
