Deception, Disappointment, San Gabriel, Markham, and Lowe
No, the title isn't a law firm: it's five peaks near Mt Wilson that I biked and hiked.
I started at Red Box and biked up the Mt. Wilson Road. Just after the 0.3 mile marker, I arrived at the Bill Reilly trailhead (it's somewhat easy to miss). That's where the Mt Disappointment Road starts. It's asphalt and closed to vehicles.
Just before the 2.0 mile marker and a cistern, there's a use trail for Mt. Deception (5,796'). I locked the bike here and started hiking. The beginning of the use trail is steep and loose, but it's a short trip to the summit. I didn't see a benchmark.
