71° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 65° in 2002.
Wallagrass’s center stands about 870 ft above sea level. Within three miles the land runs from 570 ft to 1,300 ft, a difference of 730 ft: hilly country. The highest named summit within 15 miles is McLean Mountain, about 1,940 ft, 12 miles west.
Under the town center the state geologic map shows Devonian Seboomook Formation (mudstone, sandstone), from the Early Devonian, 410 to 414 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 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone. Age: Early Devonian, 410 to 414 million years old. About 14 mi of the line.
Age: Silurian to Devonian, 359 to 445 million years old. About 4 mi of the line.
Basalt. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Wallagrass reaches the Bay of Fundy and the Atlantic Ocean by way of Square Lake, the Fish and the Saint John: about 280 river miles.
Lake on the way: Square Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wallagrass; river miles along the main stem, rounded.
Wallagrass has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about −3° in January. A normal year brings about 99 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Wallagrass normally reaches 39° and falls to 23°. The record high is 58°, in 1951; the record low 0°, in 2019. The most rain on this date, 1.18 in, fell in 2003.
Normals 1991–2020 and records since 1893 at Fort Kent, 8 miles north, 260 ft lower. NOAA, through RCC-ACIS.
