Arrow Point’s center stands about 1,080 ft above sea level. Within three miles the land runs from 900 ft to 1,210 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Pond Mountain, about 1,790 ft, 15 miles south-southwest.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 to 487 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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 10 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 9 mi of the line.

A raindrop that lands in Arrow Point reaches the Gulf of America by way of Table Rock Lake, the White River and the Mississippi: about 1,180 river miles.
Lake on the way: Table Rock Lake.
620 miles of the trip are on the Mississippi.
