Hard Rock Mining Tour: Cardinal Mill Restoration

Cardinal Mill Restoration

Getting There

This site is closed to the public for safety reasons

Boulder County purchased Cardinal Mill in April 2003 with the intent to preserve the building for the education and appreciation of future generations. Restoration of the mill is the largest project of its kind by Boulder County. Although many other sites have been restored, this property showcases many techniques used to bring a historic building back to life. The process of restoring Cardinal Mill was divided up into four phases. Three have been successfully completed with the help of multiple partners. The fourth phase is planned for the summer of 2012.

Phase 1

The Colorado Department of Public Health, through its Brownfield's Program, funded drainage improvements and the reconstruction of the west retaining wall. Building repairs were partially funded with a State Historical Fund (SHF) grant and with the help of Historic Boulder, Inc. This work included repairs to the roof, columns, beams, dormer and numerous windows.

Phase 2

When it was in operation, Cardinal Mill had two retaining walls, one on either side of the building. Both of these walls collapsed after years of neglect. In partnership with the SHF, Boulder County reconstructed the east side retaining wall and made repairs to the east elevation wall and ore cart room.

Phase 3

In 2010, Boulder County completed a third phase in partnership with the SHF. This phase included repairs to the hopper roof, the lower north and east elevation walls, the south elevation roof and numerous columns and beams.

Phase 4

Again in partnership with the SHF, this phase will include repairs to the south and southwest elevation foundations, wood frame walls, columns, stairs, floor, siding, trim and drainage, installation of 12 historically accurate windows, and repair of two large exterior doors.
