The Holden mine remediation project is a multi-million dollar effort to clean up contaminants (potential threats to human and environmental health) that were left from the Howe Sound Holden Mine era (1937-57). Rio Tinto, one of the world’s largest mining groups, is managing and paying for the cleanup under the supervision of the U.S. Forest Service. More than 120 acres, largely across Railroad Creek from Holden Village, are included in the affected area. To learn more:
