Is this the same place?
If so, is this a day or over night trip? I might be interested if the timing and weather are right.
Let me know.

P.S.~Hanta Virus...interesting.
Yeah this is the web site I used. I had to download an Excel spread sheet to convert Easting/Northing to Lat and Long but it worked out well enough. This has to be an over night trip for me as it's an easy three and a half hours from Riverside.
I'm thinking of driving out the 40 to the Needles area early morning, start the Mojave Road before lunch, tour Fort Piute, lunch, continue west and get to the Mid Hills Campground for dinner.
Day two head south off the Road to the Hole in the Wall area, tour there, return back to the Road, tour Marl Springs and lunch, then the Lava Tubes, and camp near 17-mile point on night two.
Day three cross Soda Lake (or route around it if it's still wet), through Shaw Pass, into Afton Canyon, camping at the Afton Canyon campground night three.
Day four finish the trail at Camp Cady and hit the 15 home.
