This range-front fault zone is poorly understood, and no detailed studies involving trenching have been completed. Neither the Independence fault nor the Haiwee Reservoir section has been trenched and only limited large-scale mapping has been published.
Sections: This fault has 2 sections. Further subdivision of the Sierra Nevada fault zone may be warranted based on small-scale mapping, in particular the Haiwee Reservoir section.
General: The Southern Sierra Nevada fault zone is comprised of several normal faults that form the eastern front of the southern Sierra Nevada including (from north to south) the Birch Creek fault of Clark (referred to as the Tinemaha scarp by Bateman, 1965 #5587; and Birch Mountain fault in Jennings, 1994 #2878) the Independence fault-Haiwee Reservoir "segment", the Sierra Nevada fault of Ross (1990 #5631), and the Cliff Canyon fault of Samsel (1962 #5632). The structure also has been referred to as the Sierra Nevada Frontal fault zone. Knopf (1918 #5616) was the first to map traces of the Independence fault, although he did not name the fault.
Section: Haiwee Reservoir section extends from the its junction with the southern Owens Valley fault zone [51b] south along the range front to the intersection with the Garlock fault zone  and includes the Sierra Nevada fault of (Ross, 1990 #5631) and the Cliff Canyon fault of Samsel (1962 #5632). This section of the Southern Sierra Nevada fault zone was recognized in 1938 by Jenkins (1938 #5628) and includes the Haiwee Reservoir "segment" of Wills (1988 #1690) and the Sierra Nevada fault (Inyokern area) of Jennings (1994 #2878). The term Haiwee Reservoir "section" is used for descriptive purposes. This part of the Sierra Nevada fault zone exhibits variable character along strike, but was not subdivided because of a lack of readily available information.
Fault ID: Refers to fault numbers 249 (Sierra Nevada fault zone, Haiwee Reservoir area), and 266 (Sierra Nevada fault, Inyokern area) of Jennings (1994 #2878) and fault SNV of Piety (1995 #915).

Compiled at 1:62,500 scale.
Comments: Location based on digital revisions to Jennings (1994 #2878) using original mapping by Hsu and Wagner (1990 #5627) at 1:250,000 scale; mapping by Ross (1990 #5631) at 1:125,000 scale; mapping by Samsel (1962 #5632) at 1:39,000 scale; and mapping by Wills (1988 #1690) at 1:24,000.
The Sierra Nevada fault zone is a zone of high-angle normal faults that bound the eastern front of the southern Sierra Nevada from Owens Valley to the southern end of the range, north of the Garlock fault . The northernmost fault in this zone is the Independence fault, which has a cumulative vertical displacement of approximately 1,800 m (Gillespie, 1982 #5626), which accounts for approximately half of the subsidence of Owens Valley (Bryant, 1989 #5625).
|Length (km)||This section is 131 km of a total fault length of 203 km.|
|Average strike||N6°E (for section) versus N6°W (for whole fault)|
|Sense of movement||Normal|
In the vicinity of Haiwee Reservoir, the fault forms a prominent east-facing bedrock escarpment that is 1,150 m high; the height and prominence of the escarpment decrease to the south. The fault is expressed by generally degraded scarps and breaks in slope, although locally there are well defined scarps >20 m high having maximum slope angles of about 20? (Wills, 1988 #1690).
|Age of faulted surficial deposits||Late Pleistocene (to Holocene?) alluvial-fan deposits (Duffield and Bacon, 1981 #1502; Wills, 1988 #1690).|
|Most recent prehistoric deformation||
latest Quaternary (<15 ka)
Comments: Fault related features are present on alluvial fans that were mapped by Duffield and Bacon (1981 #1502) as "young alluvium" of late Pleistocene to Holocene age. Wills (1988 #1690) concluded that the most recent paleoevent probably occurred during the late Pleistocene based on a general lack of bar-and-swale topography on the alluvium and on the discontinuous and degraded nature of fault scarps.
Between 0.2 and 1.0 mm/yr
Comments: slip-rate category (probably 0.2-1 mm/yr) is loosely based on the fact that the escarpment along the Haiwee Reservoir section is lower and less prominent than along the Independence fault section of the Sierra Nevada fault zone, which has an average slip rate of 0.35 mm/yr (Gillespie, 1982 #5626) and a 2500-m-high escarpment.
