Moscow’s center stands about 1,440 ft above sea level. Within three miles the land runs from 560 ft to 1,690 ft, a difference of 1,130 ft: steep hill country. The highest named summit within 15 miles is Moxie Mountain, about 2,920 ft, 5 miles north.
Under the town center the state geologic map shows Devonian - Silurian Madrid Formation (quartzite, calc-silicate-rock), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 14 mi of the line.
Mudstone. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Gabbro, ultramafic. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Gabbro. Age: Devonian, 359 to 422 million years old. About 1 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 Moscow reaches the Atlantic Ocean by way of Bassett Brook, the Chase Stream, the Austin Stream and the Kennebec: about 130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moscow; river miles along the main stem, rounded.
