Regional Parks Botanic Garden

Tilden Regional Park, also known as Tilden Park or Tilden, [tɪldɨn], is a 2,079-acre (841 ha) regional park in the East Bay, part of the San Francisco Bay Area in California. It is between the Berkeley Hills and San Pablo Ridge. Its main entrance is near Kensington, Berkeley, and Richmond. The park is contiguous with Wildcat Canyon Regional Park. The park is managed by the East Bay Regional Park District, created from the first land the District purchased in 1936. Tilden Regional Park was named in honor of Charles Lee Tilden, a Bay Area attorney and businessman who served on the first Board of Directors of the East Bay Regional Park District.

The Tilden Park Golf Course is a public golf course in the San Francisco Bay Area.

The 1923 Berkeley Fire was a conflagration that consumed some 640 structures, including 584 homes in the densely-built neighborhoods north of the campus of the University of California in Berkeley, California on September 17, 1923. Although the exact cause was never determined, the fire began in the undeveloped chaparral and grasslands of Wildcat Canyon, just east of the ridgeline of the Berkeley Hills, and was propelled over the ridge and southwestward just south of Codornices Creek by a strong, gusty, and intensely dry northeasterly wind. The fire quickly blew up as it swept through the La Loma Park and Northside neighborhoods of Berkeley, overwhelming the capabilities of the Berkeley Fire Department to stop it. A number of UC students fought the advance of the fire as it approached the north edge of the University of California campus, at Hearst Avenue. The other edge of the fire was fought by firefighters as it advanced on downtown Berkeley along the east side of Shattuck Avenue north of University Avenue. Firefighters were rushed in from neighboring Oakland, and San Francisco sent firefighters by ferry across the bay. Firefighting efforts were hampered by the inadequacy of water mains in northern Berkeley, where rapid development after the 1906 San Francisco earthquake had outgrown the water supply in the fire area. Firefighters trying to fight the fire connected to hydrants in the area that hissed dry and were hampered also by the predominance of cedar shake roofs. The strong and dry wind lifted burning shakes off burning houses and quickly spread the fire. The fire was halted only when the northeasterly winds died down and were replaced by the cool, humid afternoon sea breeze. The fire lines were established at Hearst and Shattuck Avenues, where larger diameter water mains delivered a reliable water supply for firefighting. Building styles in North Berkeley changed dramatically after the 1923 fire, with stucco and tile roof homes largely, but not entirely, replacing the wood-sided and cedar-shaked construction styles popularized by the Berkeley Hillside Club before the fire.As a belated result of the fire, the City of Berkeley constructed a fire station in the hills at 2931 Shasta Road (at Queens Road) just below Grizzly Peak Blvd, in 1948. In the early 2000s, this station was replaced and relocated to a nearby site just above Grizzly Peak Blvd. at 3000 Shasta Road, on the interface between the residential area and Tilden Regional Park, very close to the putative origin of the 1923 fire.

Lake Anza is a recreational swimming reservoir, located within the Tilden Regional Park, in the Berkeley Hills above Berkeley, California.

The Berkeley Hills are a range of the Pacific Coast Ranges that overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills" (from the original Spanish Sierra de la Contra Costa), but with the establishment of Berkeley and the University of California, the current usage was applied by geographers and gazetteers.

The Space Sciences Laboratory (SSL) is an Organized Research Unit (ORU) of the University of California, Berkeley. Founded in 1959, the laboratory is located in the Berkeley Hills above the university campus. It has developed and continues to develop many projects in the space sciences, including the search for extraterrestrial life (SETI@home).

The Mathematical Sciences Research Institute (MSRI) is an independent nonprofit mathematical research institution in Berkeley, California. It is widely regarded as a world leading mathematical center for collaborative research, drawing thousands of leading researchers from around the world each year.MSRI was founded in 1982, and its funding sources include the National Science Foundation, foundations, corporations, and more than 90 universities and institutions. The Institute is located at 17 Gauss Way on the University of California, Berkeley campus, close to Grizzly Peak in the Berkeley Hills.Because of its contribution to the nation’s scientific potential, MSRI’s activity is supported by the National Science Foundation and the National Security Agency. Private individuals, foundations, and nearly 100 Academic Sponsor Institutions, including the top mathematics departments in the United States, provide crucial support and flexibility. James Simons, founder of Renaissance Technologies and a University of California, Berkeley alumnus, is a long-time supporter of MSRI and serves as a member of the Board of Trustees.

The Lawrence Hall of Science is a public science center in Berkeley, California that offers hands-on science exhibits, designs curriculum, aids professional development, and offers after school science resources to students of all ages. The Hall was established in 1968 in honor of physicist Ernest Orlando Lawrence (1901–1958), the University of California's first Nobel laureate. The Hall is located in the hills above the University of California, Berkeley campus, less than a mile uphill from the University's Botanical Garden.

The Tilden Park Merry-Go-Round is a menagerie carousel located in Tilden Regional Park near Berkeley and Oakland, in unincorporated Contra Costa County. It was built by the Herschell-Spillman Company of Tonawanda, New York in 1911, and it is one of the few antique carousels left in the United States. Before arriving at Tilden in 1948, the carousel had seen service at amusement parks in San Bernardino, Ocean Beach, and Los Angeles. It is listed on the National Register of Historic Places. The Merry-Go-Round is owned by the East Bay Regional Park District.

Grizzly Peak is a summit in the Berkeley Hills above Berkeley, California. The peak is located on the border between Alameda and Contra Costa counties, within the boundaries of Tilden Regional Park, and directly behind the University of California, Berkeley campus. The peak was named for the California grizzly bear which inhabited the local area until the late 1800s. The last sighting locally was by a man who was reportedly killed by a grizzly in Strawberry Canyon below Grizzly Peak in the 1860s. The first local killing of a grizzly by a European occurred in 1772, also along Strawberry Creek just west of what is today the UC Berkeley campus, within what is now downtown Berkeley. The shooting by Spanish soldiers was recorded by Father Juan Crespi. The last grizzly in all of California was killed in the Sierra foothills east of Fresno in August 1922.Grizzly Peak became more accessible in 1932 when Grizzly Peak Boulevard was constructed along the ridge line of the Berkeley Hills. The name was extended to the previously-constructed ridge line stretch of Euclid Avenue to the north shortly thereafter. This portion was and remains a residential area of Berkeley while the original stretch is largely undeveloped. Grizzly Peak Boulevard now extends from Kenyon Avenue in Kensington in the north, through Berkeley and Oakland to an intersection with Skyline Blvd. above Oakland to the south. Before Grizzly Peak Boulevard was constructed, the location of its current intersection with Claremont (before 1892 known as Telegraph Road) and Fish Ranch Road was historically an important pass through the Berkeley Hills, before the tunnel that preceded today's Caldecott Tunnel was constructed through the hills in 1903; an inn and stage stop called the Summit House was located here. Today, Grizzly Peak is a popular location for people to get a unique view of the Golden Gate Bridge and the surrounding Bay Area. It is also common to see street luge enthusiasts in this area and down the canyon into Berkeley from Skyline Boulevard and Claremont Avenue.

KALX (90.7 FM) is an FM radio station that broadcasts from the University of California, Berkeley in Berkeley, California, United States. KALX, a community and student-run radio station licensed to the university, broadcasts in stereo with 500 watts of power. The station employs three full-time paid staff members, but is largely run by its nearly 300 volunteers, including Berkeley students and other members of the local community. The station's studios are located at Social Sciences Building on campus.

The U.S. Department of Energy (DOE) Joint Genome Institute (JGI), first located in Walnut Creek then Berkeley, California, was created in 1997 to unite the expertise and resources in genome mapping, DNA sequencing, technology development, and information sciences pioneered at the DOE genome centers at Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL). As a DOE Office of Science User Facility of Berkeley Lab, the JGI staff is composed of employees from Berkeley Lab, LLNL and the HudsonAlpha Institute for Biotechnology. The JGI also collaborates with other DOE-supported programs and facilities, such as the Environmental Molecular Sciences Laboratory at Pacific Northwest National Laboratory (PNNL), the National Energy Research Scientific Computing Center, or NERSC, and the DOE Bioenergy Research Centers.
