Chapman (1975) briefly discusses Scottsbluff points, but does not include this point type in his discussion of "types" found in Missouri. This is because this point type is very uncommon in Missouri. Bell (1958:86 - 87) reports that the length ranges from 2 to 5 inches (50 to 130 mm) with most specimens being 3 to 4 inches (75 to 100 mm). Morrow (1984:36) notes that Scottsbluff points are very rare in Iowa and estimates the age of this tool type from 7500 to 5000 BC. Sandstrom and Ray (2004:60) note that a distal end of a Scottsbluff point at the Big Eddy Site (23CE426) was associated with a radiocarbon date of 7550 - 6550 BC.
