Visit the James F. Bailey Assay Office Museum

6352 Fourmile Canyon Drive, Boulder

April 1 – October 31 from 10 a.m.- 2 p.m.

Third Saturday of each month

The James F. Bailey Assay Office Museum, located in the historic town of Wallstreet just west of Boulder, helps tell the story of hard rock mining in this area. The assay office was the place where prospectors would take their ore samples to find out whether or not they had potentially “struck it rich.” The determination of the assayer could, and often did, make or break a prospector.

The building at this site served as both an assay office and family residence, and the museum depicts both functions. Admission is free and all ages are welcome.
