The Latham 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.
4.41 inches of rain fell in two days, the most for this week of the year since records began in 1954. The next wettest, 2.96 inches, fell in 1985.
Latham’s center stands about 910 ft above sea level. Within three miles the land runs from 750 ft to 930 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 23 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Latham reaches the Gulf of America by way of Smith Creek, North Moreau Creek, the Moreau, the Missouri and the Mississippi: about 1,390 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Latham; river miles along the main stem, rounded.
Latham has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 20° in January. A normal year brings about 10 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Latham normally reaches 55° and falls to 35°. The record high is 83°, in 1999; the record low 11°, in 2018. The most rain on this date, 1.65 in, fell in 1993.
