3. Texarkana. This study area is essentially the same as
the Texarkana SMSA: however, the SMSA includes Little River Co.,
Arkansas and the 208 study area does not. The study area consists
of Miller County, Arkansas and Bowie and Case Counties, Texas.

From 1972 OBERS Projections

In this area, agriculture earnings are primarily from the pro-
duction of livestock and poultry, soybeans, peanuts and cotton.

Manufacturing earnings are principally obtained from metal
fabrication and ordinance with petroleum refining, and food pro-
cessing making up the bulk of the remainder.

4. Little Rock. The study area consists of Pulaski and
Saline Counties, Arkansas. This area is equivalent to the Little
Rock SMSA. See Arkansas Map 3.

Most of Pulaski County drains into the Arkansas River, while
Saline County is drained by the Saline River, which empties into
the Ouachita River.

Four distinct physiographic regions are represented in the
area: Fourche Mountains, Central Ouachita Mountains, West Gulf
Coastal Plain and Mississippi Alluvial Plain.

The Fourche Mountains contain several major ridges. The crest
of Rich Mountain is 2,500 feet and Fourches and Poteau mountains
are little lower. The folding is closer than in the Arkansss Valley,
but valley floors are broad and often of considerable elevation,
around Mena reaching 1,100 feet at the. center of the valley.

The Central Ouachitas are very closely folded. Some prin-
cipal mountains are Caddo, Cossatot, Trap, Crystal, and Zigzag;
the Caddo, Mazarn, Saline, and Ouachita basins are outstanding.
Elevations of 2,000 feet are common toward the center and the
west and local relief is between 300 and 900 feet.
