The Matamoras (New Matamoras) 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.
80° on Nov. 11, 2020, the hottest reading for this week of the year since 1927. Next is 79° in 1949.
Matamoras (New Matamoras)’s center stands about 630 ft above sea level. Within three miles the land runs from 600 ft to 1,120 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Owlshead, about 1,430 ft, 8 miles southeast.
Under the town center the state geologic map shows Monongahela Group (shale, siltstone, mudstone), from the Carboniferous, 299 to 324 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 27×. 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, siltstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 11 mi of the line.
Mudstone, shale, siltstone. Age: Carboniferous to Permian, 252 to 324 million years old. About 9 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Matamoras (New Matamoras) reaches the Gulf of America by way of the Ohio and the Mississippi: about 1,800 river miles.
970 miles of the trip are on the Mississippi.

Matamoras (New Matamoras) has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Matamoras (New Matamoras) normally reaches 54° and falls to 30°. The record high is 76°, in 1955; the record low 10°, in 2019. The most rain on this date, 0.93 in, fell in 1993.
