Summary
[edit]DescriptionAncient Guide (3795171893).jpg |
English: coated with lichen in dense sea fog atop a coastal hill. Made from Precambrian rocks of the Canadian Shield. From its perch in peneplained tundra, it may have been overlooking Hudson Bay when European whalers first chanced by.
Best viewed large. More inuksuit? please see my "Heart of the Arctic" gallery. www.flickr.com/photos/31856336@N03/galleries/721576236287... Notice the complete absence of trees? Ground that remains frozen all year round is called tundra. The cause is permafrost, which is the "mark of the white dragon" left behind by continental glaciation, now retreated to the nether regions of Arctic Canada. All of Nunavut lies north of the tree-line. The treeline is 200 km south of this locale while remnant polar ice caps in the High Arctic are another 1000 km north. 20% of the northern hemisphere falls within the realm of permafrost. When you are standing upon continental or alpine tundra, you are standing -in- the Ice Age. |
