The collection includes research materials gathered by Devere and Helen Helfrich as editors of the Klamath Echoes, photographs used in that publication, part of the Helfrich's personal photography collection and annotated maps they used to trace emigrant trails in the western United States. The collection is arranged into three series. Series I: Documents includes a variety of types of research materials related to the creation of the Klamath Echoes. Series II: Images includes original photographs, copies of photographs and negatives. Some photographs appear to have been used in the production of the Klamath Echoes. Others are ones created by Devere and Helen Helfrich. Series III: Maps includes topographic maps of quadrangles throughout the western United States as well as other maps covering the same geographic area. Many maps are annotated with notes about emigrant trails traces.
