KTVU-TV reports (http://bit.ly/1g5FU08) J.T. Bierdneau was severely injured when his snowmobile trapped his leg over the weekend.
After the crash, 9-year-old Bode Bierdneau decided his only choice was to ride alone across miles of snow to get help. He admits being nervous and unsure of which direction to go.
Despite having no cellphone reception the fourth grader from Marin County stayed calm, riding until he found someone with an emergency radio.
From there he led rescuers to his dad.
Bode's mother says search and rescue officials told her the boy's actions were heroic.
Bode's father was hospitalized and is expected to recover.
