Which river was historically used for fur trading in Alaska?

The Yukon River holds historical significance in Alaska, particularly for fur trading activities. During the 19th century, it served as a critical transportation route for traders and explorers venturing into the interior of Alaska. Its vast network facilitated the movement of goods, including furs harvested from the rich wildlife in the region. The river's length and accessibility made it ideal for trade between different communities and regions.

In contrast, while the Kuskokwim, Tanana, and Copper Rivers also played roles in local trade and transportation, they did not serve the same level of prominence as the Yukon in the context of the fur trade. The Yukon River's extensive tributaries and the presence of numerous indigenous populations who engaged in fur trapping and trading further underscore its importance in this historical economic activity.
