"Unknown cultural affiliations and loss of identity at high elevations." These are words used to propose the hypothesis that archaeological sites tend to lose their identity as
%3D
altitude extremes are reached. This idea is based on the notion that prehistoric people tended not to take trade wares to temporary settings and/or isolated areas. As
elevation zones of prehistoric people (in what is now the state of New Mexico) increased, there seemed to be a loss of artifact identification. Consider the following
information.
Elevation Zone
Number of Artifacts
Number Unidentified
7000-7500 ft
109
70
5000-5500 ft
137
29
Let p, be thè population proportion of unidentified archaeological artifacts at the elevation zone 7000-7500 feet in the given archaeological area. Let p, be the population
proportion of unidentified archaeological artifacts at the elevation zdne 5000-5500 feet in the given archaeological area.
