A 32-year-old Garden Valley man was treated at a local hospital for a head injury after a small boulder landed on the roof of his car as he drove Saturday afternoon on Banks-Lowman Road. He has since been released from the hospital, the Boise County sheriff said.
The incident was reported at 3:28 p.m. near milepost 4.5, which is east of Banks and near Skinny Dipper Hot Springs. Banks is about 40 miles north of Boise.
The motorist was driving a Honda Accord. The boulder — described as about the size of a two-drawer filing cabinet — hit the roof of the car, then smashed the windshield as it rolled off the vehicle, Boise County Sheriff Ben Roeber said.
The car veered across the oncoming lane of the highway and came to rest against a guard rail. A passerby reported the incident to emergency dispatch, and Garden Valley Fire and EMS responded to the scene, Roeber said.
The driver, who was alone in the vehicle, had to be extricated. He was wearing his seatbelt. The airbags did not deploy.
“They had to peel the windshield off to do the extrication,” Roeber said.
The man was transported to the hospital for a head laceration and has since been released, Roeber said.
Falling rock occurs year-round in Boise County, but it’s more frequent in the spring.
