This can be run as a Loop or Point-to-Point.

Lisa Green described the Loop:

Started at the Vivian Creek trailhead, summited all 9 peaks, from the final summit of East San Bernadino peak I backtracked to rejoin the main trail and then took the (very overgrown) Momyer trail back down the forest falls road, and ran a short road section back to the Vivian Creek TH.

Gerad Dean briefly described the route for the Summit Trail (starting at around 6700' elevation):

Todd Falker provided some context (7/17/2014):

Gregory Wagner posted the route from Shortys Well:

The landscapes of Death Valley National Park are some of the most awe-inspiring in North America.  It is a land of extremes, of low and stark desert, twisting canyons, crumbling crags of barren rock desolation, vast wilderness, and solitude.  The lowest point of Death Valley itself is Badwater Basin, which at 282 feet below sea level is the lowest point in North America.  It is also where the hottest temperatures on Earth ever recorded by man were measured.  The basin is a salt-crusted wasteland.
