The Frankston 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.
19° on Nov. 13, 2019, the coldest reading for this week of the year since 1953. Next is 24° in 1970.
Frankston’s center stands about 470 ft above sea level. Within three miles the land runs from 330 ft to 610 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Tater Hill Mountain, about 800 ft, 10 miles northwest.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 18 mi of the line.
Sandstone. Age: Middle Eocene, 38 to 48 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.

A raindrop that lands in Frankston reaches the Gulf of America by way of Caddo Creek and the Neches: about 360 river miles.
Lakes on the way: Sabine Lake and B A Steinhagen Lake.
210 miles of the trip are on the Neches.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Frankston; river miles along the main stem, rounded.
Frankston has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 34° in January. About 48 inches of rain fall in a normal year.
On November 14 Frankston normally reaches 69° and falls to 43°. The record high is 88°, in 1955; the record low 19°, in 2019. The most rain on this date, 1.14 in, fell in 1970.
