Curious Caribou, Denali National Park




I met three of these reindeer stags up a mountain today - they, like the ground squirrel, were very curious...

Arctic Ground Squirrel, Denali National Park

This little guy was very cheeky. I was 5000ft up on a mountain ridge, and he pretty much marched out of his burrow to greet me. Well, I nearly stepped on him first ,he vanished into a hole, only to pop up in another one seconds later - it was like one of those "hit them with the mallet" games. Then he just came over so close the telephoto was getting too long!

Loads more of this character...


Called Siksiks by the Inuit, the diurnal Arctic Ground Squirrel lives in colonies and is the only Arctic animal that hibernates. In the spring and summer they forage for tundra plants, seeds and fruit to increase body fat for their winter hibernation. By late summer they begin to store food in their burrows so that in the spring they will have edible food until the new vegetation has grown.

The burrows are lined with lichens, leaves and musk ox hair. During hibernation their body temperature can drop to just above freezing and their heartbeat drops. They are prey to arctic foxes and eagles.

Climate Change: Exit Glacier, Seward, Kenai Peninsula, Alaska




Exit glacier has has receded 300 metres in the past 10 years - the viewing platform for surveying the glacier would have been under several feet of ice just a few years ago. Today it's on dry land. There's quite a river flowing from underneath it, as you can see. It's very difficult to show the extent of the glacier from the ground, and still bring across a sense of its melting. That's why I used the wide-angle lens!
