The Whitley Gardens 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.
89° on Nov. 16, 2008, the hottest reading for this week of the year since 1952. Next is 86° in 1990.
Whitley Gardens’s center stands about 870 ft above sea level. Within three miles the land runs from 820 ft to 1,360 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Gold Hill, about 1,640 ft, 15 miles northeast.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. 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, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 23 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Whitley Gardens reaches the Pacific Ocean by way of the Estrella and the Salinas: about 130 river miles.
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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Whitley Gardens; river miles along the main stem, rounded.
Whitley Gardens has a cold semi-arid climate. Summer afternoons average 94° in August; winter nights fall to about 33° in December. About 12 inches of rain fall in a normal year.
