Yosemite National Park ( /joʊˈsɛmɨtiː/ yoh-SEM-it-ee) is a United States National Park spanning eastern portions of Tuolumne, Mariposa and Madera counties in the central eastern portion of California, United States. The park covers an area of 761,268 acres (3,080.74 km²) and reaches across the western slopes of the Sierra Nevada mountain chain. Over 3.7 million people visit Yosemite each year: most spend their time in the seven square miles (18 km²) of Yosemite Valley. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its spectacular granite cliffs, waterfalls, clear streams, Giant Sequoia groves, and biological diversity. Almost 95% of the park is designated wilderness. Although not the first designated national park, Yosemite was central to the development of the national park idea, largely owing to the work of people like Galen Clark and John Muir.

Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has an elevation range from 2,127 to 13,114 feet (648 to 3,997 m) and contains five major vegetation zones: chaparral/oak woodland, lower montane forest, upper montane forest, subalpine zone, and alpine. Of California's 7,000 plant species, about 50% occur in the Sierra Nevada and more than 20% within Yosemite. There is suitable habitat or documentation for more than 160 rare plants in the park, with rare local geologic formations and unique soils characterizing the restricted ranges many of these plants occupy.

Jimmie Chinn was an actor, teacher and most notably, a playwright.

Jimmie was born in Middleton, Lancashire on March 30th 1940, the only son of his beloved mother, Edie. His early years in Oldham and Manchester were to shape his writing in future years. He came to London in 1959 where he trained as an actor at the RADA and worked in many aspects of the theatre. His short and very undistinguished career as an actor led him eventually to train as a teacher at Whitelands College, Putney, where he gained an honours degree in English and Drama. He taught and became a senior teacher and housemaster at Dormers Wells School in Middlesex until becoming a full-time writer in 1984. Jimmie became increasingly loved and admired not only in the professional theatre , but also in amateur theatre circles as a fine and talented actor, director, teacher, mentor and advisor.
