Authored and compiled by the Lemhi County History Committee, the three-volume Centennial History of Lemhi County, Idaho provides an exhaustive archival portrait of settlement, mining, and indigenous displacement in east-central Idaho's rugged mountainous terrain. The comprehensive set documents the turbulent evolution of the Salmon River country from ancestral Shoshone and Bannock homelands into a rugged frontier carved by the 1860s gold rushes, ranching, and copper mining. Through extensive pioneer diaries, family genealogies, and local records, the volumes preserve the granular details of daily survival in an isolated, high-altitude basin. A keen insight drawn from the work is how multi-volume local histories compiled by community committees function as collective acts of self-mythologizing; by meticulously cataloging every homestead and mining claim while glossing over the violent removal of the indigenous population, the collection illustrates how local memory is often curated to enshrine pioneer resilience while institutionalizing the erasure of native sovereignty.
