Nevada Bureau of Mines and Geology Map 1Cg Carson city Area; A 1:24,000 scale Geology of the Genoa 7.5' Quadrangle, Douglas County. Detailed geologic mapping by Robert C. Pease in 1980. Mapping in part based on McKinney, R. F. (1975) Environmental geology of eastern Carson City, Nevada: University of Nevada, Reno, unpublished M. S. Thesis. Geologic Map of the Genoa 7.5' Quadrangle in Douglas County, Nevada, with description of 26 units. The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. Base map: U. S. Geological Survey Genoa 7.5-minuts quadrangle, 1974. To download this map and associated GIS zipped data-set, please see the links provided.

Date of Compilation: 1996. The parcels coverage was created through acquisition of digital data from third parties and the input of metes and bounds descriptions from recorded documents. Updated as new parcels are created or adjusted.

Bonham Jr., and J. L. Burnett. Geology of the South Lake Tahoe 7.5' Quadrangle, Douglas County, Nevada, Alpine and Eldorado Counties, California, with description of 25 geologic units. The GIS work was in support of the U.S. Geological Survey COGEOMAP program.

The project lead for the collection of this data in California was Terri Weist. She, along with Danielle Walsh, Shelly Blair, and other personnel, captured 30 adult female mule deer from July 2012 to November 2014, equipping the deer with Iridium satellite collars manufactured by Lotek. The data was collected from the interstate Carson River herd, where a portion of the population spends the summer months in the Sierra range of California and the winter months in western Nevada. An additional 57 deer were collared in Nevada and provided by Cody Schroeder of the Nevada Department of Wildlife. Summer range is mostly within Alpine County, California, but also extends into El Dorado County and Mono County. Winter range is confined to the California-Nevada border area in Alpine County, CA. and Douglas County, NV. GPS location data was collected between February 2012 to July 2019. Between 2 and 12 location fixes were recorded per day, with a maximum of a fix taken every 2 hours during migration sequences. To improve the quality of the data set as per Bjørneraas et al. (2010), the GPS data were filtered prior to analysis to remove locations which were: i) further from either the previous point or subsequent point than an individual deer is able to travel in the elapsed time, ii) forming spikes in the movement trajectory based on outgoing and incoming speeds and turning angles sharper than a predefined threshold , or iii) fixed in 2D space and visually assessed as a bad fix by the analyst. The methodology used for this migration analysis allowed for the mapping of winter ranges and the identification and prioritization of migration corridors in a single deer population. Brownian Bridge Movement Models (BBMMs; Sawyer et al. 2009) were constructed with GPS collar data from 45 deer, including location, date, time, and average location error as inputs in Migration Mapper. Due to the large study area and a concentration of deer movement east of Lake Tahoe in the Carson Range, the population was split into two distinct sub-herds. Twenty deer contributing 52 migration sequences were used in the modeling analysis for the Carson Range. Twenty-five deer contributing 58 migration sequences were used from the rest of the population surrounding the Carson Valley. Corridors and stopovers were prioritized based on the number of animals moving through a particular area. BBMMs were produced at a spatial resolution of 50 m using a sequential fix interval of less than 27 hours. Winter range analyses were based on data from 48 individual deer and 92 wintering sequences using a fixed motion variance of 1000. Winter range designations for this herd would likely expand with a larger sample, filling in some of the gaps between winter range polygons in the map. Large water bodies were clipped from the final outputs.Corridors are visualized based on deer use per cell, with greater than or equal to 1 deer, greater than or equal to 2 deer (10% of the sample), and greater than or equal to 4 deer (20% of the sample) from the Carson Range dataset and greater than or equal to 1 deer, greater than or equal to 3 deer (10% of the sample), and greater than or equal to 5 deer (20% of the sample) from the Carson Valley dataset representing migration corridors, moderate use, and high use corridors, respectively. Stopovers were calculated as the top 10 percent of the population level utilization distribution during migrations and can be interpreted as high use areas. Winter range is visualized as the 50thpercentile contour of the winter range utilization distribution.

Nevada Bureau of Mines and Geology OFR 03-13 (2d ed.); A 1:24,000 Preliminary Geologic Map of the Minden Quadrangle, Douglas County, Nevada, Alpine County, California. Detailed geologic mapping by Alan R. Ramelli, James C. Yount, David A. John, and Larry J. Garside. Fieldwork 1978-80, 1993-94, 2002-03. Geologic mapping was supported by the U.S. Geological Survey COGEOMAP Program and STATEMAP Program. The descriptions of bedrock rock units and tables of chemistry and age data are intended to supplement the preliminary geologic map of the Minden quadrangle. Descriptions of plutonic rocks are modified slightly from Armin and John (1983), rock age data are from Evernden and Kistler (1970), Armin and John (1983), and Robinson and Kistler (1986). Mineral modes and rock chemical data are from Armin and John (1983).

This dataset is a representation of the boundaries of the original claims (or water-righted areas) sourced from the Carson River and tributaries, as identified by the U.S. District Court in the Alpine Decree of 1980. The intended use of these data is to assist in identifying the general locations of the water-righted areas, the associated claim number, and the source map produced by the Nevada Division of Water Resources (NDWR) and the Federal Water Master during the Carson River Appurtenance Mapping Project. This mapping project was initiated in mid-1990s and continued into the early 2000's, with the final results being a series of maps identifying the location, size, and associated parcels of each claim of the Alpine Decree, signed by the State Engineer and Federal Water Master. These maps are available on the NDWR website: https://water.nv.gov/RiverMapSearch.aspx. This GIS layer should not be considered a replacement of the signed maps and exists only as guide and starting point to identify the approximate locations of the water-righted areas in comparison to modern parcel boundaries. Further research is required to determine if a particular parcel originally had decreed water rights and has retained those rights. Please contact the Division of Water Resources for more information.In order to produce a GIS depiction of the claims, the final signed maps were georeferenced to the most up-to-date version of the Douglas County and Carson City parcel datasets. Each claim and associated dry area was then digitized from the boundaries shown on the georeferenced map and attributed with the assigned claim number, a link to the claim on the NDWR Permit Database, the source map number, and a direct link the source map on the NDWR website. As this layer is strictly a visual representation, no attempt was made to match the acreages listed on the source map or in the decree for each claim.The information in this GIS layer is derived by interpretations of georeferenced maps and is being provided for convenience only. Please refer to the actual decree documentation as such records may differ from the information provided herein.
