McCausland’s center stands about 610 ft above sea level. Within three miles the land runs from 590 ft to 750 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Hopkinton, Blanding, Tete Des Morts, Mosalem formations (dolostone), from the Late Ordovician to Silurian, 434 to 447 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, mudstone. Age: Silurian, 425 to 434 million years old. About 10 mi of the line.
Dolostone. Age: Silurian, 431 to 440 million years old. About 10 mi of the line.
Dolostone. Age: Late Ordovician to Silurian, 434 to 447 million years old. About 3 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 0.4 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in McCausland reaches the Gulf of America by way of the Mississippi: about 1,490 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of McCausland; river miles along the main stem, rounded.
McCausland has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 McCausland normally reaches 48° and falls to 31°. The record high is 74°, in 1971; the record low 2°, in 1996. The most rain on this date, 1.14 in, fell in 1926.
Normals 1991–2020 and records since 1893 at Clinton No 1, 10 miles east-northeast. NOAA, through RCC-ACIS.
