The Fort Hunter Liggett 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.
92° on Nov. 16, 2008, the hottest reading for this week of the year since 1902. Next is 91° in 1933.
Fort Hunter Liggett’s center stands about 1,010 ft above sea level. Within three miles the land runs from 950 ft to 1,690 ft, a difference of 740 ft: hilly country. The highest named summit within 15 miles is Junipero Serra Peak, about 5,840 ft, 15 miles northwest.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 8 mi of the line.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 5 mi of the line.
Sandstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.9 mi of the line.

A raindrop that lands in Fort Hunter Liggett reaches the Pacific Ocean by way of the San Antonio and the Salinas: about 140 river miles.
Lake on the way: Lake San Antonio.
100 miles of the trip are on the Salinas.
Often dry. About 70% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.

Fort Hunter Liggett has a cold semi-arid climate. Summer afternoons average 85° in July; winter nights fall to about 37° in December. About 12 inches of rain fall in a normal year.
On November 14 Fort Hunter Liggett normally reaches 70° and falls to 41°. The record high is 91°, in 1933; the record low 24°, in 1955. The most rain on this date, 1.50 in, fell in 1972.
