The museum grew from the Days of '76 celebration begun in 1924 and now preserves wagons, stagecoaches, clothing, archives, and material culture connected to Deadwood's frontier commemoration.
Built in 1892 and later home to businessman and civic leader W. E. Adams, the Queen Anne residence retains architecture, furnishings, and household evidence from Deadwood's transition from mining camp to established community.
Seth Bullock developed the present hotel after the 1894 fire, adapting his business property into a substantial brick hostelry. Its later restoration connects Deadwood's commercial growth, tourism, and gaming eras.
Established in 1878 on a plateau above Deadwood, Mount Moriah holds graves associated with many communities, including prominent frontier figures, Jewish residents, Chinese residents, and people buried in potter's fields.
