Directions: From I-10 take Palm Drive north 3.1 miles toward Desert Hot Springs to Dillon Road. Turn right onto Dillon Road, drive east 1.5 miles to Mountain View Road. Turn left onto Mountain View road, drive 0.5 mile to a paved road on the right that is about 100 m before a power line. Drive east on the paved road for 200 m until it turns sharply left. Do not turn left but go straight on a dirt road. The dirt road will curve to the left and follow a wash into the hills. The center of the level line is located where a power line crosses the dirt road.
Comments: This array was established across the Mission Creek fault where that fault i s also crossed by our level line. The array was established to monitor horizontal strain on the fault following the 28 June 1992 Landers earthquake sequence.
