This is Big Bear California. I did a timed century event called Ride Around the Bear. I was just about to descend from Onyx Summit which tops out at 8400 ft. I had already climbed about 9,000 ft total gain and about 77 miles into the ride at this point. I had just finished enjoying about 60 miles of this same scenery on the way up.
I use to ride years ago all over Big Bear, though I don't recognize that area because since I rode all over Southern Calif mountains the roads all look the same! I've even did that ride about one to three years after it became a ride sometime in the early 80's, I think I rode it in 84 because I'm pretty sure it was the year I got my Trek 660.
