When will the ice roads close?


It could be weeks, it could be days...who knows?
Once they do, Tuktoyaktuk and Aklavik will only be accessible by plane or boat. :(

I hear they use sonar equipment to determine the thickness of the ice.

You can also drill holes and check the thickness, I guess -- - just like a frozen lake for ice fishing!
