Suisun Bay (bottom), Carquinez Strait (with bridges crossing it), and San Pablo Bay (upper center), with Point Reyes in the background. Andrei Sarna-Wojcicki, a geologist emeritus of the US Geological Survey (USGS), estimates that the Carquinez Strait was likely formed about 640,000 to 700,000 years ago, while much of modern California was emerging from an ice age.
Prior to this, crossing the Carquinez Strait necessitated the use of ferries. The bridge cost $8 million to build (equivalent to $140.32 million in 2023). It was the first major crossing of the San Francisco Bay [2] and a significant technological achievement in its time. Upon its completion, the span became part of the Lincoln Highway.
The U.S. Army Corps of Engineers Bay Model is a working hydraulic scale model of the San Francisco Bay and Sacramento-San Joaquin River Delta System. While the Bay Model is still operational, it is no longer used for scientific research but is instead open to the public alongside educational exhibits about Bay hydrology.
Suisun Bay (/ s ə ˈ s uː n / sə-SOON; Wintun for "where the west wind blows") is a shallow tidal estuary (a northeastern extension of the San Francisco Bay) in Northern California. It lies at the confluence of the Sacramento River and San Joaquin River, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta.
San Pablo Bay, shown with San Francisco Bay San Pablo Bay and the Carquinez Strait Panorama of San Pablo Bay from Wildcat Mountain near Sears Point in Sonoma County. San Pablo Bay is a tidal estuary that forms the northern extension of the San Francisco Bay in the East Bay and North Bay regions of the San Francisco Bay Area in northern California.
The Delta was formed by rising sea level following glaciation, leading to the accumulation of Sacramento and San Joaquin River sediments behind the Carquinez Strait, the sole outlet from the Central Valley to San Pablo Bay. The narrowness of the Carquinez Strait coupled with tidal action has caused the sediment to pile up, forming expansive ...
Carquinez Strait — part of the tidal estuary of the Sacramento–San Joaquin River Delta drain into San Francisco Bay, in the San Francisco Bay Area of California. The strait connects Suisun Bay in the delta with San Pablo Bay .
The park, which is divided into two sections, that is divided in two sections by privately owned property, is located on the southern shoreline of the Carquinez Strait and eastern San Pablo Bay and in the adjacent hills, within the East Bay region of the San Francisco Bay Area. Total area of the park is 1,400 acres (5.7 km 2). [1]
