On August 7, 1965, Torn Rinc^ and Wancy Johnson of DliRC interviewed Sttwcrt 

 Allen, a widely experienced river boeter, to deterniine the location of 

 sii^nif leant river rapios and v/hitev;ater reaches. Dr. Allen reviev/eo the oLM 

 niaps for about 1.5 hours and provided 12 locations. 



On August 9, 1965, Larry Thompson and Tom Ring conaucted interviews in 

 IJssoula with Bill rielton ana Robert Fields of the University of liontana 

 Geology Department ana Janet Johnson of the USPS, iielton and Fields reviewed 

 the full set of BLii maps (on which sites G-1 through G-45 had been plotted) 

 except for the Harlowton map. The review lasted fru.i 8:30 to 1:30, and 

 although the emphasis was on significant paleontologicoi sites, many other 

 geological natural features were identified. About SO-100 new sites were 

 recorded, beginning with site i,'o. G-432. Due to time limitations, interviewers 

 did not ask reviewers to assign value classes to any sites, although Dr. Fields 

 felt that any paleontological sites he or iielton mentioned were of statewide or 

 national significance and were significant to the scientific community. Larry 

 Thanpson met with Janet Johnson between 12:30 and 3:00. iis. Johnson dia not 

 review the BLM maps but provided .National Forest maps showing the locations of 

 ell designated and proposed Research flatural Areas (RNA's) and Special Interest 

 Areas officially designated by the USF5; these are the Coram, Cliff Lake, 

 Cottonwood Creek, and Poker Jim RNA's. All other sites are under consideration 

 but are not currently designated. Janet also provided locations of a few 

 significant ecological natural features that are not proposed as RHA's. 



On August 16, 1985, Larry Thompson and Tom Ring reviewed a portion of the 

 3LM Rivers Study maps with Ray Breuninger and l/aync './etzei for about two 

 hours. Dr. Breuninger reviewed uiaps 1-29 and Dr. './etzel reviewed i.iaps 6-2S. 

 Several dozen new sites were identified. 



On August 19, 1905, Larry Thompson end Tom Ring conducted interviews in 

 Bozeman with Dr. Steve Custer, head of the [lontana State University Earth 

 Science Department, and Dr. Cliff liontagne of the ilSU Plant and Soils Science 

 Department. Dr. John Montagne of the Earth Science Department was present for 

 review of maps 51 and 52 only, and stuuents Ginger Schmidt and Don Long set in 

 as observers. The interviews took about 3 hours and covered the complete set 

 of maps. Dr. Custer provided a list of iiontena sites that will be listed in 

 the USGS Guidebook as exemplary educational sites.

None of the experts interviewee through August 20 had thorough knowledge of 

 geological natural features in eastern iiontana, ana as a consequence, very few 

 sites had been identifieo on the map sheets for eastern iiontana. Some 

 prauising sources for eastern iiontana sites were mentionec during the 

 interviews, and included:
