The Boulder Batholith and Elkhorn Mountains Volcanics (EMV) formed concurrently during shortening between ~85-76 Ma near the end of Mesozoic Cordillera arc magmatism. Together they represent an exceptionally well-preserved and voluminous record of continental arc magmatism. We report field and analytical results from studies of the EMV and Boulder Batholith...
