The Arkansas archaeological Society in 1976 published a booklet entitled An Induction to Caddo Gap. The booklet stated
that very little archaeological research in th Ouachita Mountain region has been published and most of what has been documented was
produced before 1940. However, unpublished reports, private collections and Arkansas Archaeological Survey records indicate the region has been occupied for many thousands of
years.
In the booklet in the section entitled "history of Archaeological Work in the Ouachita Mountain Region" Ann Early of Arkadelphia stated that Paleo-Indian cultures inhibited portions of Arkansas before 8000 B.C. No definite archaeological site has yet been verified in the ouachita Mountain region, but surface collections from the upper Caddo and Ouachita Rivers have included a few fluted points of lanceolate shaped spears. It is likely they inhabited this area then.
Beginning around 8000 B.C. and lasting perhaps until 300 B.C., the Archaic cultures of hunters and gatherers who used stemmed dart points, notched river pebbles, ground axes, and a variety of chipped stone artifacts identified as knives, scapers and drills flourished in this area, according to Ann Early.
Dr. John Thomas Greer's "Essay of the Caddo River Watershed" (1985) stated that the first settlers of the Caddo region in the Archaic Period dated form 900 to 1000 B.C. In the 1920s S.D. and S.P. Dickinson found a type of chipped, double-bladed axe, typical of of the Fourche Maline culture of appoxiamately 100-800 B.C. This find was made at Buttermilk Springs in the area of Collier Creek. However, V.L. Huddleston dated the site of Brushy Creek in the 1920s at 1000 B.C. to the first century A.D. and identified it as part of the Marksville Culture. Huddleston said that culture was followed by Cole's Creek culture, characterized by its pottery and mound burial technique with the corpse in a flexed position.
Schambach, according to Ann Early, stated that after 300 B.C. the character of the material culture of peoples living in southwest
Arkansas changed. Thick undecorated pottery with bone and later clay tempering was manufactured. New styles of dart points and
chipped stone tools appeared and some new artifact were found -- such as chipped stone 'axes' and 'spades', boatstones, and clay pipes. The general
term for these cultural manifestations is Fourche Maline. The evidence accumulated so far indicates that the mountain region was occupied by
substantial numbers of people, and that new systems of social organization and making a living most likely were developed. These
systems differed from the previous Archaic life styles. Quarrying of novaculite and argillite along the upper Caddo Ouachita drainages for the
manufacture of the tools continued (Bond, 1971).

Ann early stated that at some time between 800 and 1000 A.D., a new cultural completely developed, representing a way of live based upon the cultivation of corn and other domestic plants. These societies were organized around a series of religious and socio-political beliefs which included the construction and maintenance of ceremonial centers containing temple and burial mounds. These centers did not appear to have been villages, of compact communities. The population was, instead, dispersed along river and creek valleys in small hamlet of farmstead residential sites. New styles of pottery were made, and engraved and incised decorations on finely made, highly polished potter bowls, jars, and bottles became common. Tiny, finely flaked arrow points have been found in sites, indicating that people were using bows and arrows for hunting and warfare.
However, Ann Early continued, the date of the first Caddo occupation of the Ouachita Mountain region is unkown. Asingl phase of occupation has been identified, on the basis of the appearance of certain types of pottery vessels and clay pipes, which has been given the name Mid-Ouachita. The principal component of the Adair site, some thirty miles northeast of Caddo Gap, Was that of a Mid-Ouachita phase ceremonial center.
Dr. J.T. Greer stated in his essay that Tom collier's discoveries in 1925 and Dickinson's excavations in 1927 established a new culture in this area in 1400. Shell tempered pottery was found by Dickinson along Collier Creek and Buttermilk Springs. However, some evidence exists which could suggest that this group of Indians was not of the ten tribes of the three-group confederation known as the Caddo. prior to DeSoto, however , the inhabitants of the region believed that they had "received the title of the land from the gods" (Lyon: 1952). The name Caddo is derived from French "Cadodaquois" of the eighteenth century and refers to the "Great Chiefs" of the Kadohodacho, the Caddo Indians, who may not have come into the valley proper until the late 1700s (Greer). This differs from the findings of Dr. Swanton from the Smithsonian, along with Colonel John R. Rordyce on the DeSoto Commission in 1939, who thought to Tula Indians to be Caddo Indians. (In 1541, DeSoto referred to the Indians in the area of the Caddo Gap region as Tulas.)
Historians still do not completely accept the fact that Caddo Gap was the site of the historic meeting of DeSoto and the Tula Indians. The DeSoto Commission formed in 1939, studied teh for narratives about DeSoto's stay in Arkansas. All speak of DeSoto's stay at the "hot streams" at a place named Tanico, and of a battle with the Tula Indians a short way (three days' march by the entire army) to the west/southwest. The DeSoto Commission felt that Tanico must be the area of the present-day Hot Springs, and That the Tula Indians encountered by DeSoto were in Caddo Gap..." Assuming that Tanico was near the present town of Hot Springs -- and there are no other sizeable hot springs in this vicinity -- a trail upstream to the southwest would probably have led up Big Mazarn Creek to the Caddo River just below Caddo Gap. Here the Caddo breads through a narrow opening in the in the novaculite stone ridge, and on the up-stream side the valley widens out and there are many signs of an Indian village including several mounds. This was probably the site of Tula."
De La Vega, a Peruvian who reported the DeSoto expedition, wrote that the Tula encounter occurred on a plain or level area between two rivers. Dickinson contended that eh level plain at Caddo Gap between the Caddo River and Collier Creek would fit that description. Huddleston described these Indians as having a "...cradle board deformation of the skull with a low, flat forehead" (Huddleston: 1943). Dickinson noted that their long pointed heads were "...deformed in infancy by binding" and that the adults "..had their faces tattooed, even extending the decoration over the lips" (Dickinson: 1980).
By the early 1800s most of the Indians in the area of the Caddo had migrated to Texas, and after a series of treaties (1818, 1820, 1824, 1833, 1835, 1843) and Quapaws were moved through the Caddo River region to the Red River Valley in Louisiana and later to Oklahoma. By 1859, there were evidently no Indians living in the area (Herdon: 1922).
Martin Collier, one of the oldest settlers in Montgomery County arriving soon after War of 1812, became friends of the Indians living just north of the Gap. His great-great-grandson, Argus Dutton, told how Martin made friends with the Indians. It seems Martin was somewhat of a musician. He played the fiddle, and the Indians, hearing the music coming from the Collier homestead, were lured to the "heavenly sound."
Today the statue in Caddo Gap commemorating DeSoto's 1541 visit and the mascot of Caddo Hills School District -- the Indian -- are lasting memorial to the first inhabitants of Montgomery County. Students on the Caddo Hills campus and amateur and professional archaeologists continue to find artifacts and evidence of early Indian villages up and down the Caddo River Valley.
