The beginning of the line (SC01) is 25 m south of Silver Canyon Road, 2 miles from the intersection at Highway 6.
From White Mountain Research Station: Proceed west on East Line Road to the Laws-Poleta Road. Turn right and proceed north until it deadends at Silver Canyon Road. Turn right and proceed up the fan to the start of the line.

Comments:
This line crosses the main traces of the White Mountain fault zone along the west base of the White Mountains one mile east of Laws. The line was extended 183 m eastward up Silver Canyon in 1990.

Results:
Four levelings from 1987 to 1992 are compared in an accompanying figure. The east half of the line rose nearly 3 mm in four years, relative to the west half, and then subsided about 1 mm. It is also possible to infer that the line has tilted westward abo ut 2 microradians in five years.
