Antoine’s center stands about 300 ft above sea level. Within three miles the land runs from 250 ft to 450 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Lyons Mountain, about 760 ft, 15 miles north-northwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 11 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Mudstone, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Antoine reaches the Gulf of America by way of the Antoine, the Little Missouri, the Ouachita, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 590 river miles.
310 miles of the trip are on the Ouachita.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Antoine; river miles along the main stem, rounded.
Antoine has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 30° in January. About 57 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Antoine normally reaches 64° and falls to 40°. The record high is 84°, in 1955; the record low 15°, in 2019. The most rain on this date, 2.46 in, fell in 1980.
Normals 1991–2020 and records since 1890 at Prescott 2 NNW, 15 miles south. NOAA, through RCC-ACIS.
