Managing Cultural Resources and Heritage Reading the Cultural Landscape at Dyea, Alaska Tonia Horton, National Park Service, Alaska Support Office, 240 West Fifth Avenue, Anchorage, Alaska 99501; [email protected] If, as folklorist Henry Glassie has written, “history is the essence of place,” our literacy in the cultural process of historical landscapes is of paramount importance to the American national parks.1 Without the ability to “read” landscapes as historical phenomena that continue to evolve, interpreting their stories is largely restricted to an artifactual perspective, rather than that of con- stant flux and dynamism, characteristics more typically assigned to “natural” resource paradigms rather than those of “cultural”—historic preservation and heritage production. However, as the practice of landscape architecture in historic environments methodologically progresses, the implications for understanding landscapes as critical processes, rather than static fields of arti- facts, portends some rather dramatic revision of the ways in which we can view park lands from the interdisciplinary stance of cultural landscapes. This paper is a short introduction to building a mapping infrastructure for a historic cultural landscape to provide park management with an on-going, integrated portrait of history, change, process, and place.
