The Altamont Speedway Free Festival was a counterculture rock concert in the United States, held on Saturday, December 6, 1969, at the Altamont Speedway outside of Tracy, California. Approximately 300,000 attended the concert, with some anticipating that it would be a "Woodstock West". The Woodstock festival had taken place in Bethel, New York, in mid-August, almost four months earlier. The event is remembered for its use of Hells Angels as security and its significant violence, including the stabbing death of Meredith Hunter and three accidental deaths: two from a hit-and-run car accident, and one from an LSD-induced drowning in an irrigation canal. Scores were injured, numerous cars were stolen (and subsequently abandoned), and there was extensive property damage.The concert featured performances (in order of appearance) by Santana, Jefferson Airplane, the Flying Burrito Brothers, and Crosby, Stills, Nash & Young (CSNY), with the Rolling Stones taking the stage as the final act. The Grateful Dead were also scheduled to perform after CSNY, but shortly before their scheduled appearance, they chose not to due to the increasing violence at the venue. "That's the way things went at Altamont—so badly that the Grateful Dead, the prime organizers and movers of the festival, didn't even get to play," wrote staff at Rolling Stone magazine in a detailed narrative on the event, terming it, in an additional follow-up piece, "rock and roll's all-time worst day, December 6th, a day when everything went perfectly wrong."Filmmakers Albert and David Maysles shot footage of the event and incorporated it into the 1970 documentary film titled Gimme Shelter.

Corral Hollow Pass, originally Portezuela de Buenos Ayres (Pass of Good Winds) is a low mountain pass in the Diablo Range southeast of Livermore, in Alameda County, California. This pass, at an elevation of 1600 ft, was the point where El Camino Viejo crested the range, leaving the Arroyo Seco watershed in the southeastern part of the Livermore Valley and dropping down a deep canyon into Corral Hollow near the former mining town of Tesla. The road then continued eastward along Corral Hollow Creek into the San Joaquin Valley. Today County Hwy J2 (Tesla Road/Corral Hollow Road) follows this route. This is a popular alternate route to Interstate 580 during rush hour. The name Portezuela de Buenos Ayres appears on the Diseño del Rancho Las Positas. Portezuela means "small door" in Spanish and in Mexico can mean "a pass between hills". By 1873, the name of the pass had changed and appeared on a California State Geological Survey map as Corral Hollow Pass.

The C.W. Bill Jones Pumping Plant (formerly the Tracy Pumping Plant) located 9 miles (14 km) northwest of Tracy, California, was constructed between 1947 and 1951, and is a key component of the Central Valley Project. The Delta Cross Channel intercepts Sacramento River water as it travels westwards towards Suisun Bay and diverts it south through a series of man-made channels, the Mokelumne River, and other natural sloughs, marshes and distributaries. From there, the water travels to the C.W. Bill Jones Pumping Plant, which raises water into the Delta-Mendota Canal, which in turn travels 117 miles (188 km) southwards to Mendota Pool on the San Joaquin River, supplying water to other CVP reservoirs about midway. The Tracy Fish Collection Facility exists at the entrance of the pump plant in order to catch fish that would otherwise end up in the Delta-Mendota Canal.The Jones Pumping Plant provides water service to 32 water districts within the western San Joaquin Valley, San Benito and Santa Clara counties. Of the approximate 3,000,000 acre-feet (3.7×109 m3) of water distributed, 2,500,000 acre-feet (3.1×109 m3) is delivered to farms, 200,000 acre-feet (250,000,000 m3) to urban areas, including Tracy and cities with in the Santa Clara Valley Water District, and 300,000 acre-feet (370,000,000 m3) for wildlife refuges.
