Project: Holden Mine Remediation Project – Avalanche Hazard Management Services

Client: Rio Tinto & IMCO Construction

The Holden Mine is located in a remote location near Lake Chelan in north-central Washington State. The Holden mine remediation project is a multi-million dollar effort to clean up contaminants that were left from the Howe Sound Holden Mine era (1937-57). IMCO Construction is managing the snow avalanche management program on behalf of Rio Tinto for the project site and access roads. Dynamic is supporting the program through daily avalanche forecasts for four locations within the project area. The daily forecasts are prepared by avalanche technicians who continually analyze local weather, snowpack and avalanche conditions. The technicians also provide avalanche safety training for on-site personnel and provide emergency response capacity for avalanche rescue purposes.
