Collinson Inlet is an enormous delta (70km long and 30km wide). It empties the water from much of the north western half of the island during the brief thaw. And then, it mostly dries out and reveals a large flat expanse of sand.
I was amazed by the similarity of these lands to Dubai deserts. For many kilometers I could see only sand, and in regions with less water there were small dunes as well as spindly plants blowing in the wind.
