There were three main reasons for its preparation. First, it provides a convenient reference to patent data used by staff Boundary Officers and others who may find the information helpful. Secondly, this report provides a background for newer members who may be unfamiliar with Spanish and Mexican land grants and the general circumstances surrounding the transfer of land from Mexican to American dominion. Lastly, it provides sources for additional reading for those who may wish to study further.

He worked for the railroad in New York and California, then made tanks and combines during World War I. He first worked in Yosemite starting in 1918 as a packer and guide. John was appointed park ranger in 1921 and worked in several parts of Yosemite National Park. His wife Martha assisted her husband during the busy summer season. John retired in 1956. After retiring he lived in the desert in Southern California and spent summers touring various mountain areas and National Parks with their trailer. In retirement he wrote this book, Pathways, Guardians of the Yosemite: A Story of the First Rangers (1961), and The Ahwahneechees: A Story of the Yosemite Indians (1966). His autobiography is on pages 98-99 of Guardians of the Yosemite. John’s second wife was Irene. John Bingaman died April 5, 1987 in Stockton, California. Bibliographical Information John W.

    8.3 Hydrology and Water Quality

    County of Mariposa General Plan – Volume III Technical Background Report 8.3 HYDROLOGY AND WATER QUALITY This section describes the natural and physical water environments that occur within Mariposa County, including lands managed by the United States Department of the Interior (USDI) and United States Department of Agriculture (USDA) and State of California. It addresses potential specific and cumulative impacts to hydrology and water quality of these lands that affect private property in the county, and its villages and towns. 8.3.01 HYDROLOGY The western portion of the County is relatively flat, with gently rolling hills that gradually increase toward the east. Moving eastward, the hills become more pronounced and the elevation quickly rises and falls through mountains and valleys. The elevation begins around 300 feet in the west and rises to nearly 11,000 feet in the east. Most inhabited regions are below 5,000 feet. Precipitation varies between the lower elevations in the western and southern portions of the County and the higher elevations in the eastern and northern portions of the County. Average precipitation ranges from about 15 inches annually in the lower elevations to about 50 inches at the higher elevations. Most of the annual precipitation falls between November and late April. Precipitation at the lower elevations occurs mainly in the form of rainfall with snowfall becoming the dominant form at the higher elevations. Melting of the winter snowpack at the higher elevations becomes the major source of runoff to the Merced River during the spring and summer months. SURFACE WATER HYDROLOGY Mariposa County contains three major drainage basins: the Merced River, Chowchilla/Fresno River, and a localized cluster of streams of the east valley known as the Lower Mariposa group of streams.

  • Buena Vista Lake Shrew (Sorex Ornatus Relictus)

    Buena Vista Lake Shrew (Sorex Ornatus Relictus)

    Buena Vista Lake Shrew (Sorex ornatus relictus) Legal Status State: Species of Special Concern Federal: Endangered Critical Habitat: The U.S. Fish and Wildlife Service (USFWS) designated critical habitat for the Buena Vista Lake Shrew in 2005. A revision of the critical habitat was pending as of January 2013. Recovery Planning: Recovery Plan for Upland Species of the San Joaquin Valley (U.S. Fish and Wildlife Service 1998). In 2011, U.S. Fish and Wildlife Service (USFWS) issued the Buena Vista Lake Shrew (Sorex ornatus relictus) 5-Year Review: Summary and Evaluation. In the 5-Year Review, USFWS recommended no change to the federal status of the species. Notes: No changes to status proposed or anticipated during the permit term. Taxonomy The Buena Vista Lake shrew is a subspecies of the ornate shrew. Ornate shrews are a small mammal with a body length average of 8.9–10.8 centimeters (cm) (3.5–4.2 inches), the tail length is about 3.2–4.4 cm (1.5–1.7 inches), and weighs 3–7grams (Jameson and Peeters 2004). The upper surface is brownish and the lower surface is smoke grey. The tail is not markedly bicolored and darkens toward the end (U.S. Fish and Wildlife Service 1998). The coloration of the Buena Vista Lake shrew is distinctly darker, more grayish black, than brown. The body size is slightly larger and the tail is slightly shorter (U.S. Fish and Wildlife Service 1998). Distribution General Ornate shrews occur throughout the Central Valley and Coast Range in California. The Buena Vista Lake shrew formerly occurred in the wetlands that existed around edges of Buena Vista Lake and may have also occurred throughout the Tulare Basin (U.S.

Rodney Glisan participated as a leader on some of these events. As many as 30 people participated on these hikes. They usually travelled by train to the vicinity of the trailhead, and then took motor coaches or private cars for the remainder of the way. Of the four hikes that are recorded Mount Saint Helens was the first climb undertaken by the Club. On the Beacon Rock hike Lower Hardy Falls on the nearby Hamilton Mountain trail were rechristened Rodney Falls in honor of the "mountaineer" Rodney Glisan. Trips included Mount Saint Helens Climb, July 4 and 5, 1915; Table Mountain Hike, November 14, 1915; Mount Adams Climb, July 1, 1916; and Beacon Rock Hike, November 4, 1917.

  • Buena Vista Lake Ornate Shrew Species Status Assessment

    Buena Vista Lake Ornate Shrew Species Status Assessment

    Buena Vista Lake Ornate Shrew Species Status Assessment August 2020 U.S. Fish and Wildlife Service Region 10 Sacramento, California Version 1.0 GENERAL SUMMARY In this Species Status Assessment (SSA) we (the US Fish and Wildlife Service (FWS)) assess the current and future viability of the Buena Vista Lake ornate shrew (BVLOS, “the shrew,” Sorex ornatus relictus). “Viability” refers to the ability of a species or subspecies to avoid extinction. Three factors contribute to viability: resiliency, redundancy, and representation. These refer to the ability of populations to withstand environmental and demographic stochasticity and disturbances, the ability of the species to recover from catastrophic losses, and the ability of the species to maintain representative genetic variation, thereby allowing it to adapt to novel environmental changes (Shaffer and Stein 2000, pp. 308-311). The BVLOS is a small mammal known from 11 sites in the southern portion of the San Joaquin Valley, California (the Tulare Basin). They require moist soils, dense groundcover, and diverse prey populations of insects, earthworms, and other small invertebrates. The known occupied sites constitute remnant patches of wetland and riparian habitat, which were considerably more extensive prior to development of the region for agriculture in the early- 1900s. We listed the BVLOS as endangered in 2002 and designated critical habitat for it in 2013. Important stressors influencing the viability of the subspecies include agricultural and urban development, insufficient water supply, potentially toxic levels of selenium in various water sources, pesticides, and inbreeding depression. Despite these stressors, BVLOS currently shows greater redundancy and representation than what was known at the time of listing.
