There is a pathway that goes around the perimeter of the park, which also has ADA access. Ryan 25th anniversary memorial service In 2003, on the 25th anniversary of his death, a special memorial tribute was held in Congressman Ryan's honor in Foster City, California. Ryan's family and friends including California State Senator Jackie Speier and Ryan's daughters were in attendance. The San Francisco Chronicle reported that "Over and over today, people described a great man who continually exceeded his constituents' expectations." Towards the end of the memorial service, parents of those who had died in Jonestown stood in honor of the congressman. After the service had concluded, mounted police escorted the family and friends into Leo J. Ryan Memorial Park. A wreath was laid next to a commemorative rock that honored Ryan. 2005 rededication After a three-year construction project, the park was rededicated on November 13, 2005. Notable individuals in attendance included Congressman Ryan's two daughters, as well as Foster City council members and other members of government. Jackie Speier was also in attendance.

The Lobby of Building B is open to the public during regular business hours and contains a gallery of Lucasfilm memorabilia including props and costumes from the Star Wars film series. On the patio near the entrance to Building B is a fountain featuring a life-sized statue of Yoda. Starting in 2026, there is also a General Store at Letterman a short walk from the fountain selling Star Wars products and merchandise as well as wine and food items from Skywalker Ranch. The Presidio is a former U.S. Army base. The arts center takes its name from its location on the former site of the army's Letterman Army Hospital, which was named for Dr. Jonathan Letterman, medical director for the Army of the Potomac in the U.S. Civil War. The building earned a LEED Gold certification. One of the reasons was the building was built from the recycled remains of the building it replaced, the Letterman Army Hospital. As of 2025, over 50 businesses operated out of the Arts Center. References External links Official website Lucasfilm.com: SF Campus 360 panorama of Letterman Digital Arts Center Campus

Leuzinger High School is a public high school (9th through 12th grades) in Lawndale, California, United States. It opened on January 27, 1931, with an enrollment of 268. It was named after Adolph Leuzinger in recognition of his 25 years of service on the board of trustees of the Inglewood Union High School District. The school is in the Centinela Valley Union High School District. Leuzinger High had an enrollment of 1,924 as of the 2023-24 school year. Faculty and administration As of the 2024-25 school year, the administration is headed by principal Dr. Mark Hill, and associate principals Erin Estrada, Tina Preciado, and Karen Kim. For many years, Leuzinger High School was considered to be a typical inner-city school, mostly known for producing athletes such as Kei Kamara, Marvcus Patton and Russell Westbrook. However, over the past few years, it has consistently shown academic growth spurts, largely due to its faculty and administration. Olympic mascot As Leuzinger's first senior class graduated while the 1932 Summer Olympics were hosted in and around nearby Los Angeles, the school's nickname became the "Olympians". Leuzinger was granted authorization for the school to use the Olympic name and Olympic rings trademark.

Leviathan Mine

Leviathan Mine is een verlaten zwavelmijn in de open lucht in het Sierra Nevada-gebergte, meer bepaald in Alpine County in de Amerikaanse staat Californië. De mijnplaats bevindt zich op 2100 meter boven het zeeniveau, 10 kilometer ten oosten van Markleeville, en omvat zo'n 100 hectare land. Ze wordt omgeven door het Toiyabe National Forest. De mijn werd in 1863 in gebruik genomen, ten tijde van de Comstock Lode-zilverkoorts. Tussen 1863 en 1870 werd er 500 ton kopersulfaat ontgonnen, wat gebruikt werd om zilvererts te verwerken. Na de ontdekking van zwavel in een van de mijngangen, werd de mijn verlaten. Tussen 1935 en 1941 ontgon Calpine Corporation hier 5.000 ton zwavel. In 1951 werd de mijnplaats, waar voorheen ondergrondse delfstoffen werden ontgonnen, omgevormd tot een open-pit mijn door de Anaconda Copper Mining Company. Tot 1962 werd hier 500.000 long ton zwavel weggehaald. Omdat er tijdens de laatste ontginningen zuur mijnwater naar omliggende waterlopen is gelekt, wordt de plek sinds de jaren 80 opgekuist om verdere milieuschade te voorkomen. De opkuis gebeurde eerst onder toezicht van lokale overheden, maar wordt sinds 1997 – deels onder impuls van de plaatselijke Washo-indianen – geleid door het Environmental Protection Agency. EPA erkent de Leviathan Mine sinds 2000 als een superfundsite, wat betekent dat de opkuis ervan de hoogste prioriteit heeft. Waterlopen in de omgeving, die aflopen naar de Carson, zijn namelijk al vervuild met zuur mijnwater.

Лексингтонское водохранилище

Лексингтонское водохранилище (англ. Lexington Reservoir) — водохранилище на ручье Лос-Гатос, Калифорния, США, недалеко от города Лос-Гатос. Является третьим крупным водоёмом, созданным в пределах округа Санта-Круз. Входит в состав водного района Санта-Клара и обеспечивает водой Кремниевую долину. Площадь поверхности — 1,8 км². Объём воды — 26,430 км³. Площадь водосборного бассейна — 72 км². Расположение Водохранилище находится в предгорьях гор Санта-Круз, на высоте 197 метров. Шоссе-17 проходит вдоль западного края плотины и над частью водохранилища. Дорога Алма-Бридж-роуд (Limekiln Canyon Road) проходит вокруг восточной стороны, соединяясь с HWY 17 у северной части, и снова у южной части через другие улицы. Водохранилище находится в парке округа Лексингтон-Резервуар, который включает пешеходные тропы на холмах с видом на водохранилище и Кремниевую долину. Тропа Лос-Гатос-Крик начинается у плотины и продолжается вниз по течению вдоль каньона ручья. История Плотина Джеймса Дж. Ленихана — земляная, высотой 59 метров и толщиной 300 метров. Проблемы с водой появились в 1943 году: после того, как фруктовые сады в округе начали расширяться и потребление её увеличилось, местные колодцы стали высыхать. Поэтому основной целью постройки плотины было обеспечение подъёма уровня грунтовых вод. Строительство плотины началось весной 1952 года и осенью того же года закончилось. Галерея Примечания

Lincoln University

L'Università Lincoln è un'università privata e non-profit con sede a Oakland, in California e intitolata ad Abraham Lincoln. Storia La Lincoln University venne fondata nel 1919 a San Francisco da Benjamin Franklin Lickey e dal 1926 fondata secondo le leggi californiane . Uno dei primi slogan fu "la scorciatoia per il successo" (the shortcuts to success) poiché offriva un buon pacchetto qualità-convenienza e assicurava la restituzione della retta scolastica in caso di insoddisfazione (“soddisfatti o rimborsati”). Nel 1927, la Lincoln University offriva sia corsi diurni che serali ed era collocata nell'Arcade Floor all'interno del Phelan Building di Market street a San Francisco assieme al collegio di legge e commercio e al dipartimento di corsi speciali e coaching. Un'inserzione pubblicitaria di quell'anno mostra che la Lincoln offriva corsi universitari di amministrazione e business, commercio, giornalismo, giurisprudenza, marketing, relazioni pubbliche e trading internazionale, oltre a corsi speciali, di coaching, e preparatori all'esame di abilitazione per avvocati. L'università gestiva anche programmi per le scuole superiori di preparazione ai junior college. Nel 1950, l'Internal Revenue Service riconosce all'ente lo stato di "non-profit" e nel 1961 un secondo campus venne inaugurato a San José. Nel 1987 il campus di San José si distaccò dalla Licoln University per divenire la Lincoln Law School of San Jose. Nel dicembre del 1999, la Lincoln University trasferì la propria sede a Oakland.

Kernkraftwerk Humboldt Bay

Das abgeschaltete Kernkraftwerk Humboldt Bay befindet sich in der Nähe von Eureka, Kalifornien. Die Anlage verfügt über einen Siedewasserreaktor. Der Eigentümer und Betreiber ist Pacific Gas & Electric Corporation. Reaktor Der Reaktor ist ein Siedewasserreaktor mit einer elektrischen Nettoleistung von 63 MWe und einer Bruttoleistung von 65 MWe. Geschichte Der Baubeginn war am 1. November 1960, er wurde am 18. April 1963 erstmals mit dem Stromnetz synchronisiert und ging am 1. August 1963 in den kommerziellen Leistungsbetrieb. Das Kernkraftwerk Humboldt Bay wurde 1976 unter anderem deshalb abgeschaltet, weil „Seismologen feststellten, dass es praktisch auf der "Little Salmon earthquake fault" gebaut war. Seine Konstruktion war nicht annähernd stark genug, um gegen mögliche Erschütterungen nachgerüstet zu werden, und wenn ein Erdbeben einen kritischen Teil des Kraftwerks aufbrechen würde, hätte das katastrophale Folgen haben können.“ Die endgültige Abschaltung erfolgte am 2. Juli 1976. Daten der Reaktorblöcke Das Kernkraftwerk Humboldt Bay hat einen Block: Quellen Siehe auch Liste der Kernkraftwerke
Centrale nucléaire de Humboldt Bay

La Centrale Nucléaire de Humboldt Bay était un réacteur à eau bouillante de 63 MWe appartenant à la compagnie Pacific Gas and Electric qui a été exploitée de 1963 jusqu'en 1976. Son site est au nord-ouest de la Californie. Compte tenu de sa faible taille, les inquiétudes générées par la découverte d'une faille sismique ont conduit à la fermeture du site en juin 1976. Depuis cette date elle est conservée dans un état d'arrêt sûr.

Lipetz House

Lipetz House is a house in Los Angeles designed by Raphael Soriano, and built in 1936. The building was Soriano's first residential commission, and arose from his knowledge and passion for both language and music. The main feature of the house was to be a music room with excellent acoustic properties that could accommodate Mrs. Lipetz’s Bechstein Grand piano and up to twenty guests. Soriano designed the north end of this 15-foot (4.6 m) x 32-foot (9.8 m) room as a semi circle with continuous windows, creating a real-life backdrop of the vast San Gabriel Mountain Range, for Lipetz's performances. The site itself is on the pinnacle of a hill overlooking Silver Lake. Several hundred music albums were accommodated in shelves placed under built-in seating areas, and much of the other furniture in the house was also built-in. The music room comprised nearly one third of the total 2,300-square-foot (210 m2) area of the two-bedroom house. The design is in the International Style, built with traditional wood stud construction, similar to Richard Neutra’s frame, but with one innovate technological detail - steel beams supported the ground floor. The building was chosen as one of four U.S.A. buildings for the 1937 International Architecture Exhibition in Paris, and with it Soriano won the prestigious Prix de Rome. The house is in good condition with slight alterations. Notes References “House for E. M.
