Jacksboro’s center stands about 1,080 ft above sea level. Within three miles the land runs from 1,020 ft to 2,070 ft, a difference of 1,050 ft: steep hill country. The highest named summit within 15 miles is The Flag Pole, about 3,550 ft, 9 miles south-southwest.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Jacksboro reaches the Gulf of America by way of the Clinch, the Tennessee, the Ohio and the Mississippi: about 1,670 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.
