Evidence of surges on the Barnes Ice Cap, Baffin Island
The morphology of the Barnes Ice Cap is studied on the basis of detailed topographic maps. Two anomalous areas characterized by an apparent excess of mass at lower elevations and a similar deficit at higher altitudes are identified.

Summary: | The morphology of the Barnes Ice Cap is studied on the basis of detailed topographic maps. Two anomalous areas characterized by an apparent excess of mass at lower elevations and a similar deficit at higher altitudes are identified. Local surges affecting these two parts of the ice cap could have caused this mass distribution. The moraine patterns adjacent to the ice cap show that the ice margin in the two areas has recently advanced in distinct contrast to the general retreat in adjacent areas. |
