A coroner's report identified the bodies as those of Ethan Manzano and Sophie Rayanne Edwards, both 19.
The crash site is about 20 miles from where the young couple was last seen on July 1.
Sheriff's officials said the vehicle was spotted at about 5:20 p.m. on July 6 near mile marker 72 of the Angeles Crest Highway, near Dawson Saddle Trail. Chad Keel, a Wrightwood resident who was helping search for the missing couple, told reporters he was operating the drone that spotted the wreckage and volunteers contacted the sheriff's department.

The couple were in a silver 2007 Isuzu Ascender driven by Manzano, sheriff's Deputy Shawn Du Busky said.
Some of the couple's belongings were also spotted near the crashed vehicle, which was found about 1,300 to 1,500 feet below the roadway, partially obscured by brush.
"I can't believe I'm going to be burying my son. He was only 19,'' Manzano's father, Al, said earlier this month.
"She was an amazing young lady, very intelligent and kind and just full of life and spunk," said Cheyenne Chassie, Edwards' sister.
Ethan Manzano and Edwards, his girlfriend, were visiting friends in the Newcombs Ranch area but left around 1:30 p.m. on July 1 to drive home to Apple Valley. They never arrived. The couple were planning to move to Colorado over the Fourth of July weekend.
Investigators speculate that the vehicle's driver veered off the winding roadway, sending the vehicle careening down the hillside.
Detectives are working to determine the cause of death.
CORRECTION: An earlier version of this story stated the couple left the Newcombs Ranch area at 1:30 a.m., but the couple left around 1:30 p.m.
