New data constrain the timing and character of glaciation of eastern Baffin Island, Arctic Canada. Lake sediments radiocarbon dated to between 14 and >52 ka, coupled to ¹⁰Be and ²⁶Al exposure ages >35 ka from adjacent moraines and bedrock, demonstrate that some coastal uplands remained above the limits of continental glaciation throughout oxygen isotope stage 2. At lower elevations, exposure ages from a flight of distinct lateral moraines range from 10 to 35 ka, and imply that low-gradient outlet glaciers reached the outer coast during the late Wisconsinan. Collectively, these results reconcile terrestrial evidence for the presence of ice-free refugia through the late Wisconsinan with marine evidence for extensive outlet glaciers in the major fiords and bays of eastern Baffin Island.
