Why were sled dogs once so important to survival in Alaska?

Sled dogs were crucial to survival in Alaska due to their ability to navigate and transport goods across the harsh, icy terrain where traditional vehicles could not operate effectively. They facilitated communication, trade, and travel between remote communities, especially during winter months when snow made roads impassable. Additionally, sled dogs played a key role in hunting, providing food and resources necessary for survival in the challenging Arctic environment. Their strength and endurance made them invaluable partners for Indigenous peoples and later settlers in the region.
