Descriptions of the hikes, as well as logistical information, and mistakes to avoid.
There is a vast amount of information to be posted on this subject. Peter has literally a short book already written concerning northern hiking, as well as Trail Guides to such as the Canol Road, and Crossing Alaska. There are Gear Lists (successful trekking is not All about gear), and bits of experience that may make life easier your first trip north.
To undertake any of these hikes, one might want to consider first if they have the necessary skills to safely dive into northern environments. It's hardly rocket science, but a solid measure of experience seems to be a component of successful northern trekking. This section will help explain what one is up against in the real world, and what is not so important.
