Death Valley National Park
Death Valley, CA 92328
Directions: From Furnace Creek, proceed north about 2 miles to
the entrance to the U.S. Park Service residential area. Turn right, proceed
east to Old Ghost Road, turn left and proceed north and around curve to
the intersection of Skyline Drive with Old Ghost Road. The center of line
is about 50 m north of Old Ghost Road at this poin (Fig. 1).
This line is equally disposed across the geomorphic trace of the Furnace
Creek fault on the east side of Death Valley near the old and now abandoned
Park Service sewage treatment plant. All bench marks are 1m-long copper-jacketed
steel weld rods driven nearly flush to the surface of the desert floor.
Four levelings from January 1971 to March 2000 show no height changes
among the 14 bench marks that can be attributed to vertical displacement
across the faul (Fig. 2).

leveling array across the Furnace Creek fault zone in Death Valley, Error
bars represent one standard deviation. Except for a couple unstable bench
marks (106 and 113), the line has been very stable to plus/minus a couple
millimeters in 29 years.
