Cornwall, formerly known as Cornwall Station, was an unincorporated community in Contra Costa County, California, before it was absorbed into the City of Pittsburg. It was located 7.25 miles (11.67 km) east-southeast of Baypoint and 1 mile (1.6 km) south of downtown Pittsburg, at an elevation of 39 feet (12 m) ASL.The area appears to have been named after Pierre Barlow Cornwall, an early California pioneer and president of the Black Diamond Coal Mining Company at nearby Nortonville, California from 1872 to 1904. Cornwall sprung up at the intersection of two railroads, the Black Diamond Coal Mining Railroad and the San Pablo and Tulare Railroad (the latter became part of the Southern Pacific system in 1888). The coal railroad crossed the San Pablo and Tulare line using an overhead trestle.A post office operated at Cornwall Station from 1881 to 1888. Cornwall post office operated from 1890 to 1911.The Cornwall area, together with the nearby town of Black Diamond, was officially renamed "Pittsburg" on February 11, 1911, which may explain why the Cornwall Post Office stopped operations in that same year.

Camp Stoneman was a United States Army facility located in Pittsburg, California. It served as a major troop staging area for and under the command of the San Francisco Port of Embarkation (SFPOE). The camp operated during World War II and the Korean War. The camp opened May 28, 1942 as a staging point for units deploying to the Pacific Ocean theater of World War II. The camp was named after George Stoneman, a cavalry commander during the American Civil War and Governor of California. It was decommissioned as a military post in 1954. The camp had a railroad track across the north side for receiving and shipping men. Late in the war the SFPOE experimented with embarking troops directly aboard a Liberty ship at the camp but that was not successful due to difficulties of large ship navigation to the camp. Next to the track, there were many buildings with loading docks, many of which were still there in 2017 along Bliss Avenue. There were seven barracks areas, each consisting of nine blocks (3 x 3) surrounding a mess hall. In addition to being a staging area for troops in transit, the Pacific Coast Transportation Corps Officer Training School was located at the camp. The camp also housed prisoners of war with the Italian Service Unit of the 18th Italian Quartermaster Service Company, which was based at the camp.

Browns Island (also Gwin Island or Brown Island) is a regional preserve of the East Bay Regional Park District (EBRPD) in Pittsburg, Contra Costa County, California, United States. It is an island in Suisun Bay, part of the Sacramento-San Joaquin River Delta, separated from the rest of Pittsburg by New York Slough. The 595-acre (241 ha) island is separated from Winter Island to the east by Middle Slough, and bounded by New York Slough on the south and Suisun Bay on the west and northwest. It is shown, labeled "Gwin Island", on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgold and an 1854 map of the area by Henry Lange.The East Bay Regional Park District has published a guide to the wild plants that grow on this island. The island is home to six rare and endangered plant species, and a variety of aquatic birds.

Rancho Los Medanos (from the Spanish: Rancho Los Médanos meaning Sand Dunes Ranch) was a 8,859-acre (35.85 km2) Mexican land grant in present-day Contra Costa County, California given in 1839 by Governor Juan Alvarado to Jose Antonio Mesa and Jose Miguel Garcia. The land was located at the junction of the San Joaquin River and the Sacramento River, extending eastward along the south shore of Suisun Bay to Antioch. The name "los medanos" is derived from the sand hills located along the San Joaquin River on its northern boundary. The rancho lands included present-day Antioch and Pittsburg.

Mallard Island is a small island in Suisun Bay, at the confluence of the Sacramento and San Joaquin rivers. It is part of Contra Costa County, California. Its coordinates are 38°02′31″N 121°55′07″W, and the United States Geological Survey measured its elevation as 3 ft (0.91 m) in 1981. It appears in a 1953 USGS map of the area.

Chipps Island is a small island in Suisun Bay, California. It is part of Solano County. It is also known as Knox Island, Its coordinates are 38°03′19″N 121°54′43″W by which name it appears on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgold, as well as an 1854 map of the area by Henry Lange. In 1959, the state of California used Chipps Island in a legal definition of the western boundary of the Sacramento–San Joaquin River Delta.In 1960s, during efforts to devise large-scale hydrological engineering projects in San Francisco Bay and adjacent estuaries, Chipps Island was proposed as the site of a dam across the Carquinez Strait as a "more feasible" alternative to the very expensive Reber Plan. The Chipps Island dam was estimated to cost $194,400,000 in 1963 ($1.86 billion in 2022), and retain 1,380,000 acre⋅ft (1.70×109 m3) of fresh water (which would otherwise be emptied into the Pacific Ocean). However, the project faced barriers to implementation, including potential hazards to wildlife (as it was expected to cause the flow of the San Joaquin River to reverse during part of salmon's migration period, preventing them from swimming upstream). The Sacramento Bee quoted "state fish and wildlife experts" as saying that the "seriousness of this apparently insolvable problem" was significant enough to "postpone further investigation of the other effects of the Chipps Island plan". By 1964, new plans from the Inter-Agency Delta Committee had "discarded" the Chipps Island water barrier in plans for managing freshwater in the region.Chipps Island is located close to hydrocarbon deposits, and in 1967, bids were opened for oil and gas rights on parcels in the vicinity of the island.While a duck club had once operated on Chipps Island, it was in disuse by the mid-1970s; in 1974, police arrested a "bustling" ring of illicit amphetamine producers using the abandoned structures to store large amounts of the stimulant.In the 2010s, Chipps Island was part of a large purchase of Delta land attempted by the Metropolitan Water District of Southern California (along with nearby Bouldin and Bacon Islands, as well as much of the Holland and Webb Tracts). The district was subsequently sued by several northern California environmental groups, water agencies, and the counties of Contra Costa and San Joaquin.
