The Amesti plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
88° on Nov. 15, 2008, the hottest reading for this week of the year since 1945. Next is 84° in 2005.
Amesti’s center stands about 200 ft above sea level. Within three miles the land runs from 40 ft to 520 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Loma Prieta, about 3,780 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Older Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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, less than 2.6 million years old. About 7 mi of the line.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 3 mi of the line.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
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 Amesti reaches the Pacific Ocean by way of Salsipuedes Creek and the Pajaro: about 10 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Amesti; river miles along the main stem, rounded.
Amesti has a warm-summer Mediterranean climate. Summer afternoons average 75° in September; winter nights fall to about 39° in December. About 22 inches of rain fall in a normal year.
