Youngstown’s center stands about 320 ft above sea level. Within three miles the land runs from 240 ft to 350 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Queenston Shale, from the Late Ordovician, 445 to 459 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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Ordovician, 445 to 459 million years old. About 8 mi of the line.
Dolostone. Age: Silurian, 425 to 434 million years old. About 5 mi of the line.
Sandstone. Age: Silurian, 428 to 445 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Youngstown reaches Lake Ontario by way of the Niagara: about 1 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Youngstown; river miles along the main stem, rounded.
Youngstown has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 17° in January. About 33 inches of rain fall in a normal year.
