worked out, it seems safer to use a geographic rather than a tribal 

 designation. To judge from the imperfectly known distribution of 

 the ceramic type found in Upper Republican culture sites, the culture 

 occurs in southwestern Nebraska as far west as Red Willow Creek 

 and on the North Platte River as far west as Signal Butte. It ap- 

 parently centers along the Republican and Lower Loup Valleys and

crops up under rather strange circumstances in extreme northeastern 

 Nebraska on the Missouri River. So far as known, sites of this cul- 

 ture do not occur along the Missouri River in central or southern 

 Nebraska, in which region Nebraska culture sites are numerous. The 

 Upper Republican culture probably occurs on the upper Elkhorn 

 River, but this is uncertain at present. Its suggestive but as yet 

 very poorly recorded occurrence beyond the boundaries of Nebraska 

 both to the north and to the south will be referred to later. 



These sites are located on map (fig. i).
