The naming convention for sedimentary formations follows that established by Hunt and Mabey (1966) and subsequently modified by Snow and Lux (1999) and Knott et al. Racetrack Playa is a seasonally dry lake (playa) located in the northern part of the Panamint Mountains that is famous for rocks that mysteriously move across its surface. Base of member is marked by the regionally extensive "silty unit". c. Unit is white, pale red, purple, pink, and gray, quarzite and sandstone, conglomeratic quartzite, and minor beds of light- to dark-brown micaceous siltstone. Mostly thick-bedded arid massive dark-colored dolomite, thin-bedded limestone member 500 feet thick 1 000 feet below top of formation, 2 brown-weathering shaIy units, upper one fossiliferous, about 200 arid 500 feet, respectively, below thin-bedded member. a. These observations imply that details of the structural connection between Tucki Mountain and the east end of the Funeral Mountains must be reexamined, although a probable Early Miocene age of the Tucki Mountain section can still be used to date extension at Tucki Mountain (Cemen et al., 1999). Brachiopods abundant, especially Spirifer , Cyrtospirifer , Productilla , Carmarotoechia , Atrypa. It is derived from the topography (Fig. The other period of interruption occurred between 350 and 250 Ma when sporadic pulses of mud swept southward into the Death Valley region during the erosion of highlands in north-central Nevada. Varnish does not normally form on carbonate rocks because their surfaces weather too easily. C. cornicula. This two-stage structural evolution of extensional faulting followed by strike slip is also seen in the Panamint Valley (Andrew and Walker, 2009) and, north of the Inyo Range, in the White Mountains (Stockli et al., 2003) and central Walker Lane belt (Oldow et al., 2008). b. Algal, cryptalgal, and clastic dolostone records shallow marine carbonate platform environment upper member has silty dolomite, siltstone, and stromatolitic dolomite lower member has finely crystalline, laminated, relatively pure dolomite, P.O. (2002) and, for the area west of the Panamint Range, from Saucedo et al. 1 Alluvial fan and lacustrine deposits Over time the small amount of solutes in the water accumulate to form this linear salt pan. Death Valley National Park Photos (2,214) Directions Print/PDF map Length 3.4 miElevation gain 964 ftRoute type Out & back Check out this 3.4-mile out-and-back trail near Death Valley, California. Sand dunes cover 3 square miles (8km2) of Eureka Valley, rising 680 feet (207 m) as one of North America's tallest dunes. Basement mapped by Blakely and Ponce (2002) shows only a shallow basin in Panamint Valley, west of the Panamint Range. Death Valley National Park is not a summertime destination, at least in my opinion. Shaly and silty units increase in abundance in the upper part of the formation. Fall Canyon - Death Valley National Park (U.S. National Park Service) Lee et al. The falls themselves support several small fern gullys. This modified model for evolution of Death Valley suggests a strong link between timing and style of deformation in the basin with the developing Pacific-North America plate boundary, particularly eastward propagation of this boundary.
