we followed was: 



1. Note whether a site is reported within ten kilometers of the 

 stream reach. 



2. If a site is reported within 10 kilometers, note whether it was 

 listed in the National Register of Historic Places, or determined eligible 

 for listing in the National Register by the Keeper of the Register, or 

 determined eligible for listing in the National Register by a Federal 

 Agency in consultation with the Montana State Historic Preservation Officer 

 (a "consensus determination"), or whether it has yet to be evaluated. In 

 the course of doing this work we discovered that there is no record of 

 whether a site was evaluated and found ineligible for listing in the 

 National Register. Nor was it possible to reconstruct such a record. 



3. Based on the above assessment, a set of tables was constructed (see 

 attachment C for an example). These tables summarize our original river 

 reach codings. 



4. Reaches were color-coded on the maps using the 5 originally proposed 

 "value categories" (see attachment D). 



During the second year of the project we were asked to review and evaluate 

 the study procedures while creating a computerized catalog of the Cultural 

 Resource Value Ratings. Our review resulted in two extensive modifications 

 to the final catalog: 



1. The five original value classes were reduced to the three presented here 

 under the section labeled "CRITERIA"; and, 



2. based on new information compiled and provided by the Montana State 

 Historic Preservation Office, evaluations were edited and changed with 

 some reaches being deleted and others added. 



The final computer file contains the following information for each evaluated 

 river segment: 



1. map name, 



2. river name of coded segment as listed on the map, 



3. value class for the coded segment, 



4. legal description of the starting point for the segment, and 



5. legal description of the segment end point. 



This data file is currently maintained at the University of Montana, 

 Department of Anthropology. A copy has been provided to the Montana 

 State Natural Resources Information System project at the State Library 

 in Helena, Montana.
