Around San Francisco, the explosive powder industry grew during the Civil War to supply California's gold mines, and a powder plant opened at Albany's remote Fleming Point in 1879, followed by others on the north side of Albany Hill. Nobel Depot, named for Alfred Nobel, was built near Albany Hill for rail access. Albany's shoreline became renowned for explosions until the plants were removed in 1905; the largest blast broke windows in San Francisco and was heard in Sacramento, and eucalyptus trees on Albany Hill were planted to help muffle the noise. Albany's most infamous crime occurred at Nobel Depot on November 7, 1930, when a hijacker boarded a Berkeley train, forced it to the abandoned depot, and stole $60,000, after which the depot was torn down. In 1919, the State Lands Commission granted Albany a 100-year tidelands lease to build a harbor, but the shoreline remained undeveloped and was popular for fireworks, swimming, picnicking, clam digging, fishing, and duck hunting. In the late 1930s, a horse track leased Fleming Point, and the hilltop was blasted away for fill to create the racetrack and its northern parking lot. The Golden Gate Turf Club opened for two days in 1941 before rains washed out the track. During World War II, the U.S. Navy used the site to recondition landing craft from South Pacific battles and send them out again for the next advance, and the track did not reopen until 1947. Fleming Point is now one of the few remaining stretches of the Bay's original shoreline. In the 1950s, Albany zoned its waterfront for industry, and a small dump at the base of Buchanan Street expanded rapidly after 1961, when California removed its harbor requirement from Albany's tideland lease. Over the next 25 years, construction debris created most of Albany's present shoreline, including the Albany Plateau, Neck, and Bulb. The new peninsula altered currents, waves, and winds, helping form sandy Albany Beach to the south and the bird-rich Albany Mud Flats to the north. As citizen protest against Bay fill grew, the landfill was forced to close in 1984. In 1986, California placed the tidelands in the public trust, preventing further filling of the Bay. In 1997, ending a century of private ownership, Catellus, the real estate branch of the Santa Fe Railroad, agreed to sell the racetrack to its operators and the rest of the waterfront property to the State for the Eastshore State Park, which includes about five miles of shoreline and 2000 acres of uplands and tidelands, with segments from Emeryville to Richmond linked by the Bay Trail.
