This document is updated National Historic Landmark (NHL) documentation for the Calumet National Historic Landmark in Calumet, Houghton County, Michigan. The update NHL documentation for the Calumet Historic District documents its national significance under NHL Criteria 1 and 5 as an exemplar of the United States copper mining industry in its earliest years, and the transformation of the American economy as a result of that industry. The period of national significance is from 1867 to 1923. While the lode was located in 1864, it did not begin producing copper in significant amounts until 1867. Similarly, while the company did continue mining operations as late as 1968, it is the conclusion of this nomination that the Calumet & Hecla Mining Company’s era of national significance essentially ended with the formation of the Calumet & Hecla Consolidated Copper Company in 1923, the tacit acknowledgement that the company could no longer survive or thrive on the Calumet Conglomerate Lode that had brought it to national prominence.
