I wanted to draw your attention to a new link I added to the sidebar, it's the Alaska Photo Graphics website that showcases the stunning work of photographer Patrick Endres. I'm posting some examples below, and encourage you to check out his website as well, you won't be disappointed!
The Canadian Space Agency has made it possible for armchair enthusiasts like me and you to view Aurora Borealis (aka Northern Lights) from the comfort of our own homes with its Aurora Max Project. You can view the webcam here.
The Explore North website also has a page with webcam links and some really stunning photo galleries. You can find that page here.
