Rancho Buena Ventura (also called "San Buena Ventura") was a 26632 acre Mexican land grant in present day Shasta County, California, given in 1844 by Governor Manuel Micheltorena to Major Pierson B. Reading (1816–1868).
 The land grant is named for the former name of the adjacent Sacramento River, Buena Ventura, which meant good fortune in Spanish.
 The grant extended some nineteen miles on the west side of the Sacramento River, from Cottonwood Creek on the south to Salt Creek on the north, and extended approximately three miles west of the Sacramento River the length of the grant.
 The grant encompassed present day towns of Anderson, Cottonwood and Redding.
 This was the northernmost land grant in California.
 Redding, however, was not named for Major Reading; it was named for B. B. Redding, a land agent for the Central Pacific Railroad.

 The station functioned as a World War II armament storage depot, supplying ships at Port Chicago.
 Concord NWS continued to support war efforts during the Korean War, the Vietnam War and the Gulf War, processing and shipping thousands of tons of materiel out across the Pacific Ocean.
 During World War II it also had a Naval Outlying Field at the southern edge of the base.
 It ceased being an operating airfield after World War II.
Steamboats operated in California on San Francisco Bay and the Sacramento–San Joaquin River Delta, and Sacramento River as early as November 1847, when the "Sitka" built by William A. Leidesdorff briefly ran on San Francisco Bay and up the Sacramento River to New Helvetia.
 After the first discovery of gold in California the first shipping on the bays and up the rivers were by ocean going craft that were able to sail close to the wind and of a shallow enough draft to be able to sail up the river channels and sloughs, although they were often abandoned by their crews upon reaching their destination.
 Regular service up the rivers, was provided primarily by schooners and launches to Sacramento and Stockton, that would take a week or more to make the trip.
Cottonwood Creek is a major stream in Northern California in the United States and is a tributary of the Sacramento River.
 About 68 mi long measured to its uppermost tributaries, the creek drains a large rural area bounded by the crest of the Coast Ranges, traversing the northwestern Sacramento Valley before emptying into the Sacramento River near the town of Cottonwood.
 For its entire length, it defines the boundary of Shasta County and Tehama County.
 Because Cottonwood Creek is the largest undammed tributary of the Sacramento River, it is known for its Chinook salmon and steelhead runs.
Upper Soda Springs is on the banks of the Sacramento River in Dunsmuir, California, USA.
 It consists of approximately ten acres (40,000 m²) of level ground on both sides of the River, the surrounding hillsides, and continues north along the eastern bank of the Sacramento River to the Dunsmuir City Park.
 The State of California and the City of Dunsmuir are creating a new park on this historic site.
 The Upper Soda Springs site contains a riparian ecosystem and includes its namesake mineral water springs.
 In large part because of its location on the Siskiyou Trail, the site mirrors the history of the state and of the American West.
Shore Acres Park Clubhouse (known by its former name, the Peoria Automobile Club) is the central feature of Shore Acres Park in Chillicothe, Illinois.
 The site of the clubhouse, which is located on the Illinois River, was originally part of Columbia Park, a Chillicothe city park established in 1890.
 In 1911, the Peoria Automobile Club was formed as a social and recreational organization for the automobile owners of Peoria and the surrounding cities; the club soon purchased the park from the city.
 The club built their clubhouse at the park in 1915; Peoria architects Hotchkiss & Harris provided its Classical Revival design.
 One of the club's main functions was to advocate for improved roads in Peoria and Central Illinois; in particular, they advocated for a route from Peoria to Chicago that would pass their clubhouse.
 The 1918 State Bond Issue, which established Illinois' state highway system, provided funding for this route, which became known as Illinois Route 29.
