Heath’s center stands about 1,680 ft above sea level. Within three miles the land runs from 860 ft to 1,850 ft, a difference of 990 ft: steep hill country. The highest named summit within 15 miles is Crum Hill, about 2,830 ft, 10 miles west-northwest.
Under the town center the state geologic map shows Goshen Formation (schist), from the Early Devonian, 394 to 422 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist. Age: Early Devonian, 394 to 422 million years old. About 5 mi of the line.
Quartz-feldspar-schist. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 5 mi of the line.
Granofels, schist. Age: Early Ordovician to Middle Ordovician, 471 to 487 million years old. About 3 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Arkose, siltstone, sandstone. Age: Late Triassic, 202 to 237 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 smaller units along the line are not listed.
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 Heath reaches Long Island Sound and the Atlantic Ocean by way of the West Branch North, the Deerfield and the Connecticut: about 150 river miles.
120 miles of the trip are on the Connecticut.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Heath; river miles along the main stem, rounded.
