Arkansas Geography

From a geomorphological point of view, the Arkansas territory can be divided into two large natural regions: the western highlands, which cover the Ouchita region and the Ozark Plateau; and the lowlands, which encompass the Mississippi floodplain and the Gulf of Mexico coastal plain. To the northwest of this plain rises the Crowley mountain range, a formation of the (aeolian sediments) that forms a ‘sierra’ 150 meters high and 20 kilometers wide. The coastal plain of the Gulf of Mexico begins south of Little Rock and rises almost imperceptibly to an average height of 90 meters. Much of Arkansas’ agricultural wealth is located in this grassy, ​​coastal plain.

The highlands, Ouchita and the Ozark Plateau, contrast with the rest of the territory described above, being a unit that rises 850 m above sea level. The highest point in the state, Mount Magazine (860 m), is located in this area. The highlands are a forested region, with a sparse and dispersed population. On the Ozark Plateau, an eroded plateau north of the Arkansas Valley, the Boston Mountains stand out, 600-meter hills that wind erosion has divided into staggered sections and then formed steep surfaces.


The Mississippi River, which marks the eastern border of the state, is the main receiver of the waters of most of the river currents that drain the territory of Arkansas: the Little Red, Ouchita, Arkansas and Saint Francis rivers.

It also has numerous lakes, most of them engineering works built in the northern region since 1940.

Thus, the average temperatures in winter are 2 ° C, and 27 ° C in summer. Average annual rainfall (rarely in the form of snow) is around 1,200 mm, concentrated between the months of May and December since summer storms are scarce and autumn is generally a dry season, which greatly benefits agricultural activities.
