Altamont, California

Altamont Pass, formerly Livermore Pass, is a low mountain pass in the Diablo Range of Northern California between Livermore in the Livermore Valley and Tracy in the San Joaquin Valley. The name is actually applied to two distinct but nearby crossings of the range. The lower of the two, at an elevation of 741 ft (226 m), carries two railroad rights-of-way (ROWs) and Altamont Pass Road, part of the old Lincoln Highway and the original alignment of US 50 before it was bypassed c. 1937. The bypass route travels over the higher summit, at 1,009 ft (308 m), and now carries Interstate 580, a major regional highway heavily congested by Central Valley suburbanization. Of the two railroad lines through the old pass, one is still in use: the ex-Western Pacific line built in 1908 over the pass, which is sometimes known as the Altamont Corridor, now owned by Union Pacific. It carries freight trains as well as the Altamont Corridor Express, which gives its occasional name (ACE) and operates between Stockton, Livermore, Pleasanton, Fremont, and San Jose. The other and older right-of-way was the line built in 1869 with a 1,200-foot-long (370 m) summit tunnel by the original Western Pacific Railroad (1862–1870) as part of the transcontinental railroad. After 1879, when a sea level ferry crossing at the Carquinez Strait replaced the 1869 route, it remained in use for other purposes by the Southern Pacific. In 1984 it was abandoned and deeded to Alameda County by Southern Pacific Railroad in favor of trackage rights on the aforementioned ex-Western Pacific line. From 1966 to 2008, the Altamont Pass area was home to the Altamont Speedway, which became famous as the site of the 1969 Altamont Free Concert, a large outdoor concert featuring The Rolling Stones and marred by violence. The pass is also known for the Altamont Pass Wind Farm, one of the earliest in the United States.

The Altamont Pass wind farm is located in the Altamont Pass of the Diablo Range in Northern California. It is one of the earliest wind farms in the United States. The first wind turbines were placed on the Altamont in the early 1980s by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess. The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity. Altamont Pass is still one of the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly. They were installed after the 1970s energy crisis in response to favorable tax policies for investors.

Murrieta Rocks originally named Las Tinajas, (The Jars), refers to the waterholes to be found eroded into the Vaqueros Sandstone on top of the outcrop.: 431  The location is at a large outcrop of Vaqueros Sandstone, called Murrieta Rocks, about a mile northeast of Brushy Peak just within the southern bounds of the Rancho Cañada de los Vaqueros in California. From the east, the outcrop overlooks a spring in an eastern tributary arroyo to the upper Kellogg Creek that flows down from Brushy Peak.

The Clayton-Marsh Creek-Greenville Fault is a fault located in the eastern San Francisco Bay Area of California, in Alameda County and Contra Costa County. It is part of the somewhat parallel system of faults that are secondary to the San Andreas Fault.

Brushy Peak Regional Preserve is a regional park that is part of the East Bay Regional Parks (EBRPD) and the Livermore Area Recreation and Park District (LARPD) systems. It is located in unincorporated land in Alameda County, just north of Livermore, California.

Brushy Peak, also known as Brushy Knob or Las Cuevas (The Caves), is a summit in Alameda County, California that overlooks the Livermore Valley. North of the valley, it is part of the Diablo Range. It rises to an elevation of 1,686 feet (514 m) and is the location of Brushy Peak Regional Preserve; there are guided tours to the peak itself.Historically, the peak and its immediate surroundings were used for some outdoor events, like picnics.

The South Bay Pumping Plant is located 4 miles (6 km) southwest of the Clifton Court Forebay and 10.3 miles (17 km) northeast of Livermore, CA. The plant is the only main line pumping plant for the 42.9 mile (69 km) long South Bay Aqueduct. The plant pumps from the Bethany Reservoir which is part of the California Aqueduct.

Bethany Reservoir State Recreation Area is a state park unit of California, United States, adjoining the Bethany Reservoir. It is located in Alameda County, near Livermore. Situated in the northernmost part of the San Joaquin Valley, Bethany Reservoir State Recreation Area is a popular place for water-oriented recreation, especially fishing and windsurfing. The reservoir stores water for a pumping plant on the California Aqueduct.

The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain. It achieved the first instance of scientific breakeven controlled fusion in an experiment on December 5, 2022, with an energy gain factor of 1.5. It supports nuclear weapon maintenance and design by studying the behavior of matter under the conditions found within nuclear explosions.NIF is the largest and most powerful ICF device built to date. The basic ICF concept is to squeeze a small amount of fuel to reach pressure and temperature necessary for fusion. NIF hosts the world's most energetic laser. The laser heats the outer layer of a small sphere. The energy is so intense that it causes the sphere to implode, squeezing the fuel inside. The implosion reaches a peak speed of 350 km/s (0.35 mm/ns), raising the fuel density from about that of water to about 100 times that of lead. The delivery of energy and the adiabatic process during implosion raises the temperature of the fuel to hundreds of millions of degrees. At these temperatures, fusion processes occur in the tiny interval before the fuel explodes outward. Construction on the NIF began in 1997. NIF was completed five years behind schedule and cost almost four times its original budget. Construction was certified complete on March 31, 2009, by the U.S. Department of Energy. The first large-scale experiments were performed in June 2009 and the first "integrated ignition experiments" (which tested the laser's power) were declared completed in October 2010.From 2009 to 2012 experiments were conducted under the National Ignition Campaign, with the goal of reaching ignition just after the laser reached full power, some time in the second half of 2012. The campaign officially ended in September 2012, at about 1⁄10 the conditions needed for ignition. Thereafter NIF has been used primarily for materials science and weapons research. In 2021, after improvements in fuel target design, NIF produced 70% of the energy of the laser, beating the record set in 1997 by the JET reactor at 67% and achieving a burning plasma. On December 5, 2022, after further technical improvements, NIF reached "ignition", or scientific breakeven, for the first time, achieving a 154% energy yield.

Vasco Caves Regional Preserve is a natural and cultural protected area located on the eastern slope of Mount Diablo, on Vasco Road within eastern Contra Costa County, California. It was created to preserve wildlife habitats, California chaparral and woodlands, native plant communities, and Native American rock art.

Ulmar (formerly, Ulmar Siding) is a former unincorporated community now annexed to Livermore in Alameda County, California. It lies at an elevation of 551 feet (168 m).
