Drift prospecting in high relief areas of the Cordillera requires consideration of paleo-ice-flow reversals. This means rethinking the manner and degree to which glacial ice eroded, transported and deposited surficial sediments. The regional context, geomorphic landforms and sediment stratigraphy identified in the Seagull Creek valley suggest that late-glacial up-valley ice flow, although relatively short in duration, may have been the controlling process for glacial transport and deposition in this area. This interpretation has important implications for mineral exploration programs that utilize glacially transported materials for various forms of geochemical analysis. Geomorphic landforms and glacial dynamics responsible for reverse (up-valley) ice flow in Seagull Creek valley have important implications for mineral exploration on the Ross River Minerals Tay LP gold-copper property.
