Wheelock’s center stands about 2,640 ft above sea level. Within three miles the land runs from 1,280 ft to 2,620 ft, a difference of 1,340 ft: steep hill country. The highest named summit within 15 miles is Burke Mountain, about 3,240 ft, 13 miles east.
Under the town center the state geologic map shows Gile Mountain Formation - rhythmically graded member (quartzite, phyllite, mica-schist), from the Early Devonian, 404 to 414 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 16 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 3 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Mica-schist, quartzite. Age: Early Devonian, 394 to 422 million years old. About 1 mi of the line.
Granite, granodiorite. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.
Quartzite. Age: Silurian to Early Devonian, 394 to 425 million years old. About 1 mi of the line.

Wheelock straddles the St. Lawrence Divide. Rain on the west side runs to the St. Lawrence River; most of the rest goes to Long Island Sound and the Atlantic Ocean.
From the center of town, a raindrop reaches Long Island Sound and the Atlantic Ocean by way of Miller Run, the Passumpsic and the Connecticut: about 310 river miles. One that lands on the west side reaches the St. Lawrence River by way of Flagg Brook, the Lamoille and the Richelieu: about 200 river miles. The St. Lawrence carries it on to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wheelock; river miles along the main stem, rounded.
