Blackrock/High Rock Canyon - 4x4 Trip

Something completly different: I am looking at visiting Blackrock Desert area over the Memorial Weekend. Gravel roads, moderate challenges. Lots of Driving.
Potential Itinerary:
Friday night meet at Pig Rock area. (GPS Coordinates later)
Saturday:
West side Pyramid Lake
Sand Pass to Gerlach. Highway to Empire to top off fuel
Return to Gerlach and West Side of Blackrock Desert (Playa may be too wet to cross . . .)
Camp Mud Meadows Reservoir or Soldier Meadow Hot Springs
Sunday:
Fly Canyon to High Rock Canyon
Through High Rock to Stevens Camp or Massacre Ranch for the night
Monday:
Vya
Cedarville (re-fuel)
Alturas and Hwy 395 South to home)
The camping will most likely be primitive. There are toilet facilities at Double Hot Springs ( if the playa is dry enough to cross), and at the cabin and at the hot springs in Soldier meadow, Stevens Camp and at Massacre Ranch. However, plan for no facilities. Water and food for the entire trip.
Blackrock Desert and High Rock Canyon were notable points on the Lassen-Applegate emigrant trail to California.
Limited to 4 additional vehicles. Message with any questions . . .
