A 1a ter Mesozoic event may be repre- sented by f!iuHs in this area. The older fold set (F1) consists of generally northeast-trending, upright to southeast-overturned folds. A younger fold set (F~) is t.. superimposed upon and 1ocally refolds F, folds. F2 consists of gen­ erally northwest-trending, upright to northeast-overturned folds with steeply southwest·-dipping axial pl~ne clE-avage. r}~uncation of some F folds the Mm.lt'rt;;.in batholith in the Nelson Range indicates 2 by Hunter The style of r-.) " folds along portions of the intrusive co1tact suggests that emplace- v~ i rnent of the batholith locally appressed and deflected pre.-existing folds. Based on their orientation, sense of vergence and relative age, r 1 folds are believed to be temporally and structurally related to th~ Last Chance thru~t system (Middle (?) Triassic to Early Jurassic). folds are correlated with other northwest-trending fo1ds of pre-Middle Jurassi~ age ~hich occur throughout the ranges immediately east of the Sierra Nevada. Some nm·thwest-striking fauits in this area apparently are intruded by dikes of the Independence swarm and thus may be pre-Late Jurassic in age. If so, these faults may be related to a broad) north1:1est-trending zone of fractures and left-slip faults of Middle to Late Jurassic age which tr2nds obliquely acr-oss this region. viii INTRODUCTION The Nelson Range trends northwest across the southwest corner of the Ubehebe Peak quadrangle in Inyo County, Califon·ria (fig. 1). Paleozoic rocks exposed along the southwest flank of the range and in the eastern foothills of the southern Inyo ~1ountains consist of over 2100 m (6880 ft} of Mississippian thr·ough Permian mat~ine stata. These rocks have been intruded in the Nelson Range by the Hunter Mountain batholith of late Early Jurassic age. Initial regional mapping of the Ubehebe Peak quadrangle and vicinity by McAllister (1952~ 1956) demcn:itrated the predominance of north-and northwest-trending folds of Mesozoic age in the Paleozoic rocks of the Nelson Range and southern Inyo Mountains. Locally developed east­ trending folds, as we11 as northwest-trending folds roughly parallel to the intrusive contact in the Nelson Range, were believed to be the result of forceful batholithic emplacement (McAllister, 1956). North­ west-trending folds were also reported in the Darwin quadrangle to the south (Hal1 and MacKevett, 1962) and in the Cerro Gordo district to the west (l~erriam~ 1963), ·and these also were believed to have ·formed dudng emp1acement of nearby plutons. Recent geological investigations in areas adjoining the Nelson Range indicate that many folds pre·-date plutonism and that the ranges immediately c-ast of the Siert~a Nevada contain one of the most complete records of Mesozoic deformation in eastern California (Dunne and Gulliver> 19'16; Dunne and others. 1978). In the Talc City Hills, Gulliver (~971. l976a, l976b) reports three phases of Mesozoic folding, at least two of which are genetically related to faults of tegiona1 1 2 I 168 " . ~ "-r"- . ~..... ~ CD \!\ .,.. ~ ""' "?

In the Darwin Hills, Dunne and Gulliver (1976) recognized four deformational phases which span the Mesozoic aild are characterized by folds and faults of distinctive style and geometry. Elayer (1974) reports four phases of folding near Cerro Gordo in the southern Inyo i'<lountains, although, subsequent work by Nora (1978) in this same area suggests a somewhat simpler stru~tura1 history. The purpose of the present investigation was to determine whether the Nelsen Range and nearby eastern slopes of the southern Inyo Mount­ ains share a similar history of multiple superposed Mesozoic deformation as reported in adjoining areas. Preliminary work shov.Jed that this area bears the imprint of at least two phases of early Mesozoic deformation (Werner, 1978). These deformational phases are believed to be gene­ tically and temporally correlated with major structural features which define a portion of an early Mesozoic orogenic belt in eastern Califor­ nia (Burchfiel and others, 1970). ~1ETHOD The study area (fig. l) which consists of approximately 100 sq km, was mapped during 70 days of field work between June, 1976 and Septembe~ 1977. Field data were plotted directly on portions of the Ubehebe Peak, Darwin> and New York Butte 15' tcpographic quadrang1es which had been enlarged to a scale of 1:15,625 (approx. 4 inches to 1 mile). Field investigation was augmented by the use of color aeri31 photographs (scale 1:20,000) taken in December, 1975 for the Bureau of Land Manage- ment. Preoaration and contoudng of stel~eor.et diagrams \vas a~ded by the use of the Ca'lifornia State University~ Northridge (CSUN) CDC 3170 4 computer using the FORTRAN program PETROFAB (Werner, 1977}. ROCK UNITS PALEOZOlC STRATIGRAPHY Paleozoic sedimentary rocks which crop out w·ithin the study area consist of over 2100 m (6880 ft) of marine limestone, shale, siltstone, sandstone, and conglomerate which range in age from f~ississippian to Permian. Mississippian units are primarily fine-grained, siliceous clastics and include the Perdido Formation and Rest Spring Shale. Penn­ sylvanian and Permian strata, originally mapped as Bird Spring Formation by ~tcA11ister (1956), are assigned to the Keeler Canyon and Owens 'Ialley Formations and comprise a monotonous sequence of interbedded limestone and shale. This investigation indicates that rapid lateral variations in lithology character·ize several portions of the late Paleozoic section. Field evidence suggests that these variations can be attributed to ·iocal unconformities, possibly due to submadne erosion, as weii as facies changes associated with the transition from shelf carbonates to foreland bastn deposition which characterized this region during the late Paleozoic (Stevens and others, in preparation). Figure 2 shows composite stratigraphi: columns for both the north­ ern and southern ha"lves of the study area. These stratigraphic columns were compiled from field notes and cross sections. Lithologies are much generalized and thicknesses are approximate.

  • Interest and the Panamint Shoshone (E.G., Voegelin 1938; Zigmond 1938; and Kelly 1934)
    109 VyI. NOTES ON BOUNDARIES AND CULTURE OF THE PANAMINT SHOSHONE AND OWENS VALLEY PAIUTE * Gordon L. Grosscup Boundary of the Panamint The Panamint Shoshone, also referred to as the Panamint, Koso (Coso) and Shoshone of eastern California, lived in that portion of the Basin and Range Province which extends from the Sierra Nevadas on the west to the Amargosa Desert of eastern Nevada on the east, and from Owens Valley and Fish Lake Valley in the north to an ill- defined boundary in the south shared with Southern Paiute groups. These boundaries will be discussed below. Previous attempts to define the Panamint Shoshone boundary have been made by Kroeber (1925), Steward (1933, 1937, 1938, 1939 and 1941) and Driver (1937). Others, who have worked with some of the groups which border the Panamint Shoshone, have something to say about the common boundary between the group of their special interest and the Panamint Shoshone (e.g., Voegelin 1938; Zigmond 1938; and Kelly 1934). Kroeber (1925: 589-560) wrote: "The territory of the westernmost member of this group [the Shoshone], our Koso, who form as it were the head of a serpent that curves across the map for 1, 500 miles, is one of the largest of any Californian people. It was also perhaps the most thinly populated, and one of the least defined. If there were boundaries, they are not known. To the west the crest of the Sierra has been assumed as the limit of the Koso toward the Tubatulabal. On the north were the eastern Mono of Owens River.

  • California Rare & Endagered Birds
    California brown pelican Pelecanus occidentalis californicus State Endangered 1971 Fully Protected Federal Endangered 1970 General Habitat: The California brown pelican uses a variety of natural and human-created sites, including offshore islands and rocks, sand spits, sand bars, jetties, and piers, for daytime loafing and nocturnal roosting. Preferred nesting sites provide protection from mammalian predators and sufficient elevation to prevent flooding of nests. The pelican builds a nest of sticks on the ground, typically on islands or offshore rocks. Their nesting range extends from West Anacapa Island and Santa Barbara Island in Channel Islands National Park to Islas Los Coronados, immediately south of and offshore from San Diego, and Isla San Martín in Baja California Norte, Mexico. Description: The brown pelican is one of two species of pelican in North America; the other is the white pelican. The California brown pelican is a large, grayish-brown bird with a long, pouched bill. The adult has a white head and dark body, but immature birds are dark with a white belly. The brown pelican weighs up to eight pounds and may have a wingspan of seven feet. Brown pelicans dive from flight to capture surface-schooling marine fishes. Status: The California brown pelican currently nests on West Anacapa Island and Santa Barbara Island in Channel Islands National Park. West Anacapa Island is the largest breeding population of California. In Mexico, the pelicans nest on Islas Los Coronados and Isla San Martín. Historically, the brown pelican colony on Islas Los Coronados was as large as, or larger than, that of recent years on Anacapa Island.

It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs.

    Society for the Conservation of Bighorn Sheep Sheep Sheet - Volume 2 – September 2020 www.desertbighorn.org Before the project began, collection box area in sad shape After the project: a formal, robust spring box Redwood Spring Box Installed at Castle Mine Spring By Debbie Miller Marschke SCBS has been working to improve the natural spring at the Castle Mine location for many years. Mining ruins and a dilapidated cabin remain as evidence that this spring has a history of folks teasing out the precious water from this location. There is always an overgrowth of vegetation at the spring which is proof positive that the spring is active, even if the flow rate is minimal. Bighorn Sheep biologists have GPS data from collared sheep in the mountain range that prove the Bighorn Sheep wander along the backbones of the ridges; occasionally they visit this spring but they mainly depend on the big game guzzlers to the north of this location. Nevertheless, each water location in a mountain range is crucial in the network of water sources available. SCBS crews have dug out and cleared the guzzler intake Johnson screen several times on previous occasions which has been very frustrating because a spring box had never been installed. The water seeps from the entrance of an old mine adit in the side of a hill. The hill face and adit entrance are unstable, and thus dirt caves in and has buried the intake system time and time again. On the weekend of May 15-17, 2020, a modest SCBS strike force sought to make one final but meaningful attempt to boost water output from Castle Mine spring.

    Panamint/Argus Description/Location: Panamint/Argus, subdivided into 2 units: Panamint Lake Unit and the Mountain Unit. Located between Argus Wilderness and Death Valley National Park. Nationally Significant Values: Ecological: This area encompasses an essential movement corridor which links wildlife habitats in the China Lake Naval Air Weapons Station and Argus Wilderness to those protected by the Death Valley National Park. This corridor was developed by the SC Wildlands group (Science and Collaboration for Connected Wildlands). SC Wildlands was part of a team that worked with the California Departments of Transportation and Fish and Game on a statewide habitat connectivity effort from which this unit was developed. The habitat suitability and movement needs of over 40 selected focal species were used in this process. Desert Bighorn sheep and Mojave ground squirrels are two of those focal species that occur here. In addition, the area provides excellent habitat for foraging and nesting of numerous raptor species, including golden eagles and prairie falcons. The Slate, Argus, and Panamint Mountain ranges would be included in this large unit. These ranges provide habitat for Nelson's desert bighorn sheep, Townsend’s big‐eared bats, and the federally threatened Inyo California towhee. The abandoned mines in this area have historically housed the largest maternity colonies of Townsend’s big‐eared bats in the Western Mojave Desert. It is likely that unsurveyed mines in the Slates and Argus Range also house large colonies. The area also includes Mohave ground squirrel (MGS) core habitat within the MGS Conservation Area. This is 1 of only 11 core population centers.
