Rio Vista’s center stands about 20 ft above sea level. Within three miles the land runs from -20 ft to 160 ft, a difference of 180 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Kirby Hill, about 340 ft, 12 miles west.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 10 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Rio Vista reaches San Francisco Bay and the Pacific Ocean by way of the Sacramento: about 14 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rio Vista; river miles along the main stem, rounded.
