Police were called around 10:30 a.m. about the accident. The 15-year-old and 2 friends were riding on a steep section of a trail in Johnson's Pasture when he lost of his bicycle, witness Michael Balchunas said.
Paramedics responded and requested the airlift due to head trauma from the fall.
"He had some bruising on his legs and cheekbone," Mr. Balchunas said. "But it didn't look too bad."
The helicopter from Los Angeles County landed in the Claremont Wilderness Park, just northwest of the condominiums on High Point in Claraboya. The teenager was carried by paramedics to the helicopter.
There's no official word yet on the nature of his injuries.
