I grew up, my first 34 years in Crowley Lake just south of Mammoth Lakes. There are endless two tracks in that area. As well as the Bishop area. All around Crowley, to the top of the mountains, Laurel Lakes, McGee mountain, Wheeler Ridge is a great 50 mile round trip pretty demanding ride, starts near Toms Place, white mountains, coyote ridge, I could go in for days. That is just a few of the spotlight areas. I have put tens of thousands of miles in that area and lots of nearby Nevada.
