On google maps, a few roads off of HW 89 will show in this area. This is GCD rec area. The main road is show as a trail head for “Stateline Canyon” (does not show on Apple Maps). It’s a wash board gravel road with only 3 or 4 slightly sandy spots on the side of the road. The marked location is the largest with room for 4-5 vans/cars (look for abandoned tires). Never saw another vehicle. Leave no trace.
