In 1992, an intensive survey of the MiTi-1 locality recorded 87 concentrations of lithic artifacts exposed on remnant ground surfaces on bench and ridge areas on the west side of Thunder River valley at its confluence with the Mackenzie River Valley. Most of the 25 surface features excavated had lithic artifacts distributed in a collapsed burnt humic layer and the top of the underlying mineral soil. The excavated lithic assemblage includes 98 tools and 36 282 pieces of debitage. The artifact assemblage and hearth features suggest general occupation activities in addition to quarrying and artifact manufacture. The antiquity of the archaeological deposits is undetermined due to a lack of datable material.
