The northeastern Colorado ranch is located in a large bowl-shaped basin. A small intermittent creek drains the basin to the southeast. The creek is fed cool water from several natural springs along its route. The creek was quite prolific in the past, meandering and braiding its way tens of miles until joining the South Platte River. Over the last hundred years, agricultural use caused a few of the creek's water sources to dry up.
The headwaters of the creek butt up against sandstone bluffs of the Oligocene-Miocene geological age. In the past, finding extinct mammal fossils was as easy as pie; it is not so easy these days. It was also easy to find prehistoric artifacts a few decades back, but now I have to work for every artifact. In the past, I found chipping debris galore, fire-blackened rocks eroding out of embankments, and several artifacts on any given day. Over the past forty years of hunting the ranch, I have discovered everything from Clovis to historical Indian artifacts and every prehistoric culture between. It would be a shorter list for me to name the High Plains projectile point types I have not discovered on the ranch versus listing the projectile point types that I have discovered. But over the last decade, my artifact finds have dwindled. I still hunt the ranch two or three times a year, and occasionally I land a nice artifact, but the glory days of artifact hunting are gone. However, I still have a few stories about artifact hunting on the ranch.
In September 2003, I returned to the High Plains from my home in Texas to hunt artifacts. Originally, I was not scheduled to hunt the ranch because I wanted to let natural erosion catch up with my artifact-hunting pressure. However, I found an extra day in my schedule with nothing planned so I told myself, “Why not hunt that ranch?” And I am glad I did. I found a couple of beautiful end scrapers, several broken projectile points, a mano, several other worked pieces, and the "prize of the day." This story is about that "prize of the day" and the people who probably made it.

The "prize of the day" was a beautiful 1.8-inch-long Washita arrow point eroding from an embankment approximately twenty to thirty meters down the hill from the prehistoric rockshelter in Figure One. To this day, it is one of the finest Washita points that I have ever found (Figures Two and Three).

Central Plains Tradition
From around A.D. 900 to A.D. 1000, the people of the Missouri River areas of Kansas, Nebraska, and South Dakota, in what archaeologists call the Central Plains tradition, were influenced by the prolific Mississippian culture to the east. The people of the Central Plains tradition shared similar technologies, subsistence patterns, and socio-economic systems across a wide geographical area. Archaeologists have traced the Arikara, Mandan, Pawnee, and other historical Indian tribes along the Missouri River Basin to the Central Plains tradition.
The Republican River is a small tributary of the Missouri River with its headwaters originating in eastern Colorado. The river flows from its headwaters in Colorado across northwestern Kansas into southwestern Nebraska and then back into north central Kansas before joining with the Kansas River, which ultimately joins the Missouri River.
The discovery by archaeologists of prehistoric hamlets in central and eastern Nebraska and Kansas gave rise to a phase within the Central Plains tradition called Upper Republican (Strong 1934). Based on radiocarbon dating, the Upper Republican phase began around A.D. 1000 and lasted until around A.D. 1400. There are various hypotheses as to what happened to the people of the Upper Republican phase but that topic is outside the scope of this article.
Horticulture, hunting, and gathering drove the Upper Republican economy and lifestyle. Archaeological evidence indicates that the Upper Republican people grew maize, gourds, squash, beans, and sunflowers. They cultivated their crops with hoes made from the scapula bones of bison. Evidence shows that the Upper Republican people on the Central Plains supplemented their farming and hunting with wild plant harvesting, fishing, and mussel gathering.
The Upper Republican phase on the Central Plains was characterized by substantial earth-lodge dwellings (Wedel 1961:94). The people lived in rectangular to semi-rectangular lodges built slightly below the ground surface. The lodges ranged from 500 to 1200 square feet with covered entrances facing south or east, away from the prevailing winter winds. A central fire pit and one or more subterranean cache pits were located within each lodge. Posts outlined the perimeters of each lodge with four or more postholes found in the middle for roof support. The lodges were randomly placed along mostly stream terraces and exhibited little or no central planning. (Steinacher and Carlson 1998).
The main chipped stone tool assemblages of the Upper Republican phase were associated with hunting, butchering, and animal hide processing. Artifact assemblages included bifaces of various sizes and shapes for cutting and chopping, end scrapers, engravers, and drill forms. The projectile points associated with the Upper Republican phase were usually small and triangular, with side-notches and tri-notches. When found on the High Plains, artifact hunters like myself classify those small triangular side-notched and tri-notched projectile points as Washita and Harrell arrow points. Figure Four is a photograph of examples of Washita and Harrell arrow points that the author surface found in northeastern Colorado. The centerpiece is the Washita point photographed in Figures Two and Three.

| Figure Four - Examples of side-notched and tri-notched arrow points surface recovered on the High Plains of northeastern Colorado. The author assumes these points originated in the High Plains Upper Republican phase. Is that a good assumption? |
Upper Republican ground stone tools included pipes, abraders, hammerstones, spheres, manos and metates, nutting stones, and disks. Bone implements included bison scapula hoes, splinter awls, eyed needles, fishhooks, beads, tubes, and shaft wrenches. Less dominant bone tools included engraved bison bone toes, eagle bone whistles, and in one case an engraved human skull fragment (Steinacher and Carlson 1998; Wedel 1986:108). I have found examples of some of those ground stone tool types on the High Plains but since other prehistoric cultures used them as well, I cannot attribute my surface finds to the Upper Republican phase.

| Figure Five - from Cassell (1997:214) |
A thinner-walled, globular ceramic pottery design from the Upper Republican phase replaced the thicker-walled, conoidal ceramic pottery design from the earlier Plains Woodland tradition (Figure Five). According to Ellwood (2002:34), Upper Republican people constructed ceramic pottery using a lump or patch accretion method. Then they finished by rolling a cord-wrapped, dowel-like instrument along the surface to seal the junctures. Raw materials for the vessels consisted of locally derived crushed sedimentary rock, clay, and granite. Upper Republican ceramic pottery was jar- to pot-sized and exhibited high shoulders with narrow necks and collared or braced rim mouths (Wedel 1986:106).
The Upper Republican potters often decorated the collars with two to eight incised horizontal lines, repeated triangles, or excised nodes. The surface finish exhibited short, choppy cord marks, with obliteration or smoothing of the cord marks, especially near the bottom of the pot. Handles or lugs were rare on Upper Republican ceramic pottery.
Wedel (1986) proposed that Upper Republican ceramic pottery might have been used to boil meat or vegetables, such as maize, beans, and wild tubers; or for dry storage; or as water containers. The Upper Republican ceramic pottery design from the Central Plains carried over onto High Plains sites which I discuss in the next section.

Sigstad (1969:18-19) identified two classes of Upper Republican ceramic pottery. Class I Frontier Ware exhibited collared rims while Class II Cambridge Ware exhibited flared rims. Figure Six exhibits Upper Republican potsherds which I surface recovered on the High Plains. On July 6, 1986, I found the rim fragments in the center and right of the lower row. I discovered them near a north-facing rock shelter on private land near Cedar Point in eastern Colorado. Note the incised horizontal lines near the bottom of each fragment. Both pieces appear to have originated from the same ceramic pot. I recovered the other two rim fragments from multicultural sites in Weld County, Colorado. Those rim fragments fall within Sigstad’s Class II Cambridge Ware category also.
I have found hundreds of potsherds while surface hunting for artifacts in northeastern Colorado and southeastern Wyoming. The potsherds are usually small, measuring one inch by one inch or smaller. On that scale, it is nearly impossible for me to tell whether the potsherd originated from an Upper Republican or Plains Woodland ceramic pot. Identification of the culture is much easier if the potsherd is from a distinctive rim or is large enough to see the curvature of the original pot.
Elwood (2002:40) suggested Upper Republican and Plains Woodland ceramic pottery can be differentiated using form and surface finish. While Plains Woodland vessels were conoidal in shape, Upper Republican vessels were globular in shape (Figure Five). That only helps if the potsherds are large enough to determine the curvature of the original pot. Elwood stated that while Plains Woodland exhibited clear and deep cord marks, Upper Republican cord marks were often choppy, smoothed over, or partially obliterated. Figure Seven shows a few potsherds I found in northeastern Colorado. Note the clear and deep cord marks on most of the pieces. I believe all of the potsherds in the figure originated as Plains Woodland pottery except perhaps the bottom pieces on the left which could be Upper Republican.

The High Plains Upper Republican Phase
High Plains collectors and professionals discovered artifacts in rock shelters, on buttes and bluffs, and along stream terraces similar to those documented at the Upper Republican hamlets in central Kansas and Nebraska. The rock shelter sites were quite small and occupation zones consisted of diffused middens containing chipping debris, animal bone fragments, hearths, and ashy soil. The butte and bluff campsites offered excellent views but meant hauling water upslope and those sites did not offer protection from cold northerly winds.
Archaeologists investigated and documented several High Plains Upper Republican campsites in eastern Colorado including the Peavy, Smiley, Agate Bluff, and Happy Hollow rock shelters and the Buick, Kasper, Biggs, and Donovan open campsites. Radiocarbon dating suggested occupations between A.D. 1000 and A.D. 1400 (Wood 1990).
In comparing the original Upper Republican sites in central Kansas and Nebraska with the High Plains Upper Republican sites to the west, Laura L. Scheiber (2006:135) wrote, "These western sites are known more for what they lack (houses, hoes, and corn) than for what they possess." The Upper Republican people on the Central Plains held different lifestyles than those on the High Plains. To the east, the Upper Republican people placed heavy emphasis on horticulture and permanent dwellings while in the west there was little or no horticulture and permanent dwellings. Thus far, the only evidence of any horticulture for the High Plains sites was a single maize kernel buried four and a half feet deep at the Agate Bluff site in northeastern Colorado. Cassell (1997) also noted that bison scapula hoes, prominent on the Upper Republican sites on the Central Plains were completely absent on the High Plains sites. During my research, the closest I found for permanent dwellings on High Plains Upper Republican sites were the pit houses archaeologists investigated at Cedar Point Village (Wood 1971:55-56). Wood (1971:81) suggested that "Cedar Point pit houses are not comparable to any of the five-post foundation structures reported by Gunnerson for Dismal River."

| Figure Eight - Washita-lookalike arrow point surface recovered on private land in southwestern Wyoming on 9/3/2013. I cataloged this arrow point as a Plains Side-Notched. |
When I surface recover a Washita or Harrell projectile point in eastern Colorado or southeastern Wyoming, I assume the High Plains Upper Republican people made that point. Is that a good assumption? Probably not since I find Washita and Harrell lookalikes outside the known geographical range for High Plains Upper Republican. Figure Eight is such an example. I discovered that 1.1-inch long Washita lookalike point on September 3, 2013, on a private ranch west of Baggs in southwestern Wyoming. It looks like a Washita arrow point in every aspect but I found it well outside the geographical range for High Plains Upper Republican. In southwestern Wyoming, that type of projectile point is not called a Washita, it is called a Plains Side-Notched.
The side-notched point in Figure Eight is not an anomaly. I have found many Washita and Harrell lookalikes across the High Plains. Washita and Harrell point lookalikes are found all across Wyoming, Montana, and the Dakotas to the north, and as far south as Oklahoma and Texas. Similar point types are found in the Southwest and across the Great Plains. Collectors and archaeologists have christened them with names such as Plains Side-Notched, Plains Tri-Notched, Billings, Desert Sierra, Desert Delta, Reed, Peno, Cahokia, Irvine, and Emigrant, just to name a few.
Were those projectile point designs a convergent technology developed independently from the Upper Republican phase? Did those projectile point designs originate in the Central Plains and spread from there or did those designs originate someplace else? Does the lack of High Plains sites underestimate the geographical range of the Upper Republican phase? Were the Washita and Harrell projectile points I photographed in Figures Three and Four made by High Plains Upper Republican people? Those are unanswered questions I found no answers to during my research.
Of course, people have opinions, but opinions are only sometimes backed up with facts. Bottom line, side-notched and tri-notched projectile points like Washita and Harrell were widely used, far beyond the known range of High Plains Upper Republican. The design swept across the entire western part of the continent. Surface finding Washita and Harrell projectile point types in the geographical range for High Plains Upper Republican is still not conclusive evidence for the presence of High Plains Upper Republican.

Figure nine was a small south-facing rockshelter I discovered in eastern Colorado in the early 1980s. On my initial visit, I found ash, charcoal, burned bone, and chipping debris on the ground in and around the shelter. Most of the rockshelters I have investigated faced south. Facing south meant the rockshelter captured sun rays in the winter and the rock behind the rockshelter blocked those nasty winter winds. That particular rockshelter was small and could only accommodate a single family. The roof of the rockshelter looked unstable so I contacted a local university to see if they were interested in investigating it. The university never bothered to get back to me, so I proceeded with my salvage operation.
In that rockshelter, I found a lot of chipping debris and burned bone. I also found a couple of bone awls, several Late Prehistoric projectile points including Plains Woodland and Upper Republican types, scrapers, and a couple of flake knives. On the pasture in front of the rockshelter, I discovered several Late Prehistoric and Late Archaic artifacts. The roof collapsed on the rockshelter fifteen to twenty years ago, burying the remaining occupation levels under massive sandstone boulders.
Theories of Origin for High Plains Upper Republican
Wedel (1961:102) suggested that there was a need for more evidence to be collected and analyzed from the High Plains sites before questions of origin could be answered. He stated that it was impossible to determine whether Upper Republican material on the High Plains sites marked seasonal hunting camps for the Upper Republican horticulturists out of the Central Plains.
Wood (1969) proposed that the Upper Republican campsites on the High Plains were occupied by Upper Republican earth-lodge dwellers from the Central Plains during seasonal hunting forays. Wood's evidence was based on a lack of burial sites, horticultural tools, and permanent structures at the High Plains campsites. Wedel (1970:7-10) and Reher (1973:119) argued that Wood's theory was illogical. Reher refuted Wood's claim that earth-lodge dwellers would travel two hundred miles across excellent bison hunting grounds to hunt other bison on the High Plains.
By comparing artifact inventories reported from historical Pawnee hunting trips to the artifact assemblages in Upper Republican campsites on the High Plains, Roper (1990) argued that the artifact assemblages on the High Plains were too culturally diverse and well-represented to be from temporary hunting camps.
Steinacher and Carlson (1998:248) summarized three hypotheses for the High Plains Upper Republican sites. The first hypothesis was the Wood proposal above where earth-lodge dwellers from the east made periodic or seasonal trips to the High Plains to replenish their resources. The authors noted that raw material originating in the High Plains was used almost exclusively on stone tools discovered in some Upper Republican sites in Kansas and Nebraska. That raw material could only get to the Central Plains from the High Plains by trading or transporting it.
Using geochemical analysis, Roper et al (2007) determined that a few of the ceramic pots discovered in High Plains Upper Republican sites used clay from the Medicine Creek area of southern Nebraska. That was evidence that at least a few Upper Republican ceramic pots were transported from the Central Plains to the High Plains. The researchers also noted that during the excavation of House 5 in the Medicine Creek area of Nebraska investigators discovered a large quantity of Flattop Chalcedony from eastern Colorado. That provided evidence of raw material movement from the High Plains to the Central Plains during the Upper Republican phase.
The second hypothesis suggested by Steinacher and Carlson was that some people from the east gave up their sedentary horticultural lifestyles on the Central Plains and took up nomadic hunter and gatherer lifestyles on the High Plains. That is a logical hypothesis if we assume that some humans around A.D. 1000 were as adventurous as the pioneers who settled in the western United States in the 1800s. Humans have a desire to live their lives the way they want. Some people prefer a predictable lifestyle while other people like taking bigger risks. The High Plains Upper Republican people might have abandoned their farming hamlets along the tributaries of the Upper Republican River in Kansas and Nebraska to head west just like the pioneers of historical times did.
The third hypothesis that Steinacher and Carlson suggested was that indigenous people already occupying the High Plains established trade with the Upper Republican people in the east. We already know that Upper Republican people along the Central Plains ended up with raw material originating from the High Plains, and ceramic pottery from the Central Plains ended up in High Plains Upper Republican sites. Was that material shared between two groups from the same phase or two entirely different phases or societies?

Conclusions
Is it a good assumption that High Plains Upper Republican was the western extension of the Upper Republican phase of the Central Plains?
Based on archaeological evidence, the Central Plains and High Plains people lived vastly different lifestyles. On the Central Plains, horticulture was an important part of the economy while on the High Plains horticulture appeared to play little or no role. Even with the different lifestyles, there was a relationship between the High Plains and Central Plains people during the Upper Republican phase. At High Plains sites, archeologists found Upper Republican pottery manufactured with clay from the Central Plains, and at Central Plains sites, archaeologists found raw material originating on the High Plains. We know that the Upper Republican people from the Central Plains and High Plains used the same styles of side-notched and tri-notched projectile points.
That is clear-cut evidence that material moved between the Central Plains and High Plains populations during the Upper Republican phase. However, the evidence of material movement does not define the social relationship between two groups of people. Were those people kinfolk or not related? Did the Upper Republican phase on the Central Plains use the High Plains as outposts or for seasonal hunting trips? I found no smoking guns or evidence that conclusively answered those questions.
When excavating a Late Prehistoric site on the High Plains, archaeologists have three markers used to identify the presence of Upper Republican. First, the age should fall between A.D. 1000 and A.D. 1400. Second, small, triangular side-notched and tri-notched projectile points should be in the artifact inventory. And most importantly, the distinctive Upper Republican ceramic pottery must be present. If there is evidence of horticulture (corn), working hoes made from bison scapula, and permanent dwellings that is a bonus, even though Scheiber (2006:135) reminded us that, "These western sites are known more for what they lack (houses, hoes, and corn) than for what they possess."
Surface finds of Upper Republican material are an entirely different ball game. For one thing, it is impossible to accurately date materials out of archaeological and stratigraphic context. Secondly, the presence of side-notched and tri-notched arrow points of the Washita and Harrell variety may or may not be associated with High Plains Upper Republican. The most important artifact for determining the presence of High Plains Upper Republican is the distinctive ceramic pottery. Of course, the potsherds must be large enough to differentiate them from earlier Plains Woodland ceramic pottery. Of course, finding an entire High Plains Upper Republican pot would be a surefire indicator. I have been searching for that well-preserved ceramic pot for decades. Unsuccessfully, I might add. Finding a well-preserved Upper Republican ceramic pot is as rare as finding moose feathers.
