Many years ago I almost went over the side about 500ft from those coordinates. I lost control on piles of cinders - at night it was very hard to discern them from the tar strip crack patching Caltrans does/did. The only thing that stopped me was a low berm that Caltrans created by putting asphalt over a dirt berm at the roadside. I stopped so close to the edge that I had to be careful exiting the vehicle - my wheels came to rest halfway up the berm. There's a long fairly steep chute there and only one small tree would have potentially stopped me.
There's now a guardrail there, but I can still faintly see the divots my wheels left in the berm beneath it. The guardrail does not extend across the entirety of the chute, I assume because that's the inside of a turn. That seems to be the pattern of Caltrans' guardrail installations. It's too bad these young people passed away there. I've given that spot many a long look...it's where the road almost got me.
I even have an ancient video of my skid marks taken the next day - roughly 20 years ago now. 180-degree spin and slid backwards/sideways into the berm:
