GENERAL FEATURES
Stewart County, which occupies the northwest corner of the region
described in this report (pi. 1), is bounded on the west by the Ten­
nessee River, on the north by Kentucky, on the east by Montgom­
ery County, and on the south by Houston County. Its density of
population, as in the other counties along the east side of the Ten­
nessee River Valley, is less than in other parts of north-central
Tennessee. The county seat, Dover (estimated population, 406), is
on the south bank of the Cumberland River near the geographic
center of the county.
Although the county lies in the physiographic district known as
the Highland Rim plateau (pp. 16-18), only a part of its northeastern
quadrant shows any extensive level tracts such as are characteristic
of that peneplain. Most of the county is deeply dissected by the
subparallel tributaries of the Tennessee River and of the Cumber­
land River, which traverses the county from southeast to northwest.
Even in this dissected area, however, the crest of the divide between
the Tennessee and Cumberland Rivers and the crests of many of the
subordinate ridges have not been reduced below the peneplain level.
These peneplain remnants rise southward from an altitude of about
525 to 600 feet above sea level along the northern boundary of the
county to nearly 750 feet above sea level along its southern boundary.
The master streams are about 300 to 335 feet above sea level, so that
the total relief in the county is about 450 feet. A part of this relief
is expressed in open mature valleys at the heads of tributary streams,
but by far the greater part in narrow youthful trenches of the master
streams and of the lower reaches of the tributaries.
