Great report.
Sorry to call you out like this, but this is becoming a bigger and bigger problem every year and needs to be said.
Your recovery.
You were off trail.
In a closed area.
Image is from the BLM Desert Access Guide, Ridgecrest map.
If anyone is reading this and wanting to drive the escape trail, please do not continue east off road across the flats in the Panamint Valley.
The correct and legal routes heading into the Panamint Valley from the bottom of Fish Canyon/Escape Trail/p168 is either turning North (left) on p170 which will take you to Ballarat Road roughly half way between the town of Ballarat and Panamint Valley road, or turning South (right) and continuing on p168 to the intersection of Wingate Road a few hundred feet North of the start of Goler Wash/p152.
