The Pilot-Grouse Creek rift belt, at least 90 miles long, extends northward between Pilot Valley and the Upper Raft River valley and constitutes a major lineament in the earth's crust along which the graben blocks were displaced downward relative to the adjacent mountain blocks. In the southern part...

Outcrops of the volcaniclastic rocks in the surroundings of Missouri Buttes and Devils Tower. (A) Rounded block of granite photographed at the DT-2 site. (B) The valley between Missouri Buttes locally hosts blocks of volcaniclastic deposits as long as 2 m. Hammer is 30 cm long. (C) A large rounded boulder of granite (in foreground) was found in phreatomagmatic deposits (in background) at a saddle between the two northern Missouri Buttes. (D) Outcrops of volcaniclastic deposits ∼0.8 km west of Missouri Buttes show angular clasts, as much as 30 cm long, of various lithologies encased in earthy brown matrix; a metamorphic rock clast is next to the hammer. The hammer is 30 cm long. Letters in the lower left corner of pictures refer to sampling sites in Figure 3.

None of the dams shows evidence of catastrophic failure; all blocked the river and diverted water over or around the dam crest. The net effect of the dams was therefore to inhibit rather than...

Map of Lake Mead area showing modification of the Duebendorfer et al. (1998) reconstruction. Steps in reconstruction are as follows: (1) Restoration of 20 km of left-slip movement along the Hamblin Bay fault and about 5 km north-south shortening places Frenchman Mountain near the present Gale Hills. (2) The River Mountains stratovolcano complex (part of the Frenchman Mountain structural block) is moved a minimum of 7 km east along a combined Las Vegas Valley shear zone–Saddle Island detachment-transfer fault system. (3) About 15 km of extension was accommodated north of Lake Mead by a system of strike-slip and normal faults. (4) Frenchman Mountain is restored to a hanging-wall position over the Gold Butte block. Abbreviations are as in figure 1.

Oblique Google Earth image of Section 1 of the Black Mountains Fault Zone (BMFZ; view east from 5.6-km elevation; October 30, 2010 imagery date) showing both the eastern and western sections along with the locations of study Sites A, B, and C relative to the Amargosa River flood plain. The Southern Death Valley Fault Zone (SDVFZ) is also shown along with Shoreline Butte basalt at the northern end of the Confidence Hills and Cinder Hill. Undifferentiated Miocene-Pleistocene sedimentary rocks are of the Miocene-Pliocene Furnace Creek Formation and the Pliocene-Pleistocene Funeral Formation. Arrows show relative motion on strike slip faults; relative motion on normal fault is shown by up-thrown (U) and down-thrown (D) blocks.

Surprise Valley landslide exposed in Bonita Creek. (A) Toe viewed toward the west showing a subhorizontal detachment surface on top of the Rampart Cave and Sanup Plateau Members (double red lines). Red lines extend about 1 km. (B) Cross-section A-A' showing present geometry. (C) Cross-section restored to ca. 2.1 Ma. Location of the cross-section is shown in Figure 2 and Supplemental Plate S1 (text footnote 1). Geologic unit symbols are defined in Figure 4. Black lines show the ground surface and formation contacts. Double red lines represent the Rampart Cave and Sanup Plateau Members; green line shows the top of Redwall Limestone. Dashed lines in both cross-sections show paleotopography, including the projected Cogswell Butte to the west of the section line. Dashed lines at right show pre-slide Toreva blocks in the restored cross-section.
