Abstract

Karst features are widespread in the Canyon Range of the Mackenzie Mountains and the Norman Range of the Franklin Mountains, N.W.T. Collapse and solution dolines, large closed depressions, streets, pinnacles, small caverns, and a variety of karren forms have developed on dolomites and evaporites of Cambrian to Devonian age. These features are most pronounced on the Lower Devonian Bear Rock Formation, a dolomitic solution breccia. Surface drainage in this area is poorly integrated, with numerous sinking streams and ponds, seasonally flooded depressions, and springs. Infiltration into the subsurface is impeded by the presence of permafrost; however, observations indicate that recharge into the aquifer through dolines is significant. Hydrological, hydrochemical and oxygen-18 data indicate the majority of sinking waters travel via the relatively shallow pathways of the epikarst with some waters circulating to greater depths
