Baytown’s center stands about 950 ft above sea level. Within three miles the land runs from 670 ft to 1,050 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Big Mound, about 1,130 ft, 10 miles east-northeast.
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 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 9 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.

A raindrop that lands in Baytown reaches the Gulf of America by way of Lake Mallalieu 175 and the Mississippi: about 1,810 river miles.
Lakes on the way: Lake Pepin and Lake Mallalieu 175.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Baytown; river miles along the main stem, rounded.
Baytown has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 9° in January. About 29 inches of rain fall in a normal year.
On November 14 Baytown normally reaches 43° and falls to 28°. The record high is 72°, in 2025; the record low 1°, in 1919. The most rain on this date, 1.03 in, fell in 1926.
Normals 1991–2020 and records since 1871 at St. Paul Downtown Airport, 12 miles west-southwest, 250 ft lower. NOAA, through RCC-ACIS.
