Kings Park West’s center stands about 390 ft above sea level. Within three miles the land runs from 260 ft to 470 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Popes Head Formation - Old Mill Branch Metasiltstone Member, from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. 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: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Granite. Age: Cambrian to Ordovician, 445 to 542 million years old. About 5 mi of the line.
Metasiltstone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 3 mi of the line.
Melange. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 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. 9 smaller units along the line are not listed.

A raindrop that lands in Kings Park West reaches Chesapeake Bay and the Atlantic Ocean by way of Pohick Creek and the Potomac: about 110 river miles.
95 miles of the trip are on the Potomac.
