Final answer:
In the Canadian Shield region, people can travel on foot across the snow in the winter using snowshoeing or cross-country skiing.
Step-by-step explanation:
In the Canadian Shield region, there are two common ways that people can travel on foot across the snow in the winter: snowshoeing and cross-country skiing.
Snowshoeing involves wearing snowshoes, which are large, flat devices that distribute the weight of the person over a larger area, preventing them from sinking into the snow. This allows for easier walking and maneuvering in snowy conditions.
Cross-country skiing involves using skis to glide over the snow. It requires more skill and technique than snowshoeing but allows for faster travel across longer distances.
