Final answer:
The Yukon Territory is famous for the Klondike Gold Rush of 1897, a massive movement of prospectors to the region following the discovery of gold, inspired by similar events like the California Gold Rush and the mining of the Comstock Lode.
Step-by-step explanation:
The Yukon Territory became famous in 1897 due to the Klondike Gold Rush. This event was marked by the large number of prospectors moving to the Yukon in hopes of finding gold, following a similar pattern to previous rushes, such as the California Gold Rush, where people sought wealth and the promise of a better life. The Klondike Gold Rush triggered a migration that transformed the area, much like the earlier California Gold Rush, where large strikes of gold were also found. Similarly, the discovery of the Comstock Lode in Nevada led to a boom in the mining of silver and later of gold in other western territories, contributing to the cycles of economic growth and decline.
