Truro’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 160 ft, a difference of 160 ft: gently rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Granite, gneiss, and schist, undivided (granite, gneiss, schist), from the Neoproterozoic, 542 to 1,000 million years old.
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.
Granite, gneiss, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 17 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.
Rain that falls on Truro runs straight into the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Truro; river miles along the main stem, rounded.
