MALIBU — A California teen who made Headlines as a pioneering mountain climber could face charges for allegedly Surfing up the Pacific Coast Highway on top of a car on his way to school.

Authorities say 18-year-old Johnny Strange of Malibu was photographed Wednesday by a bus passenger after climbing out of a BMW’s passenger window and standing on the car as it moved with traffic in a 50 mph zone.

Strange was later confronted by sheriff’s deputies in the halls of Malibu High School. Prosecutors are deciding what charges to file.

Strange made headlines last summer when he climbed Mt. Everest and then Australia’s Mt. Kosciuszko, becoming the youngest person to summit the highest peaks on all seven continents.
