Was a physical geographic factor that affected the Klondike Gold Rush?

One significant physical geographic factor that affected the Klondike Gold Rush was the harsh climate of the region. The extreme cold and heavy snowfall limited the mining season and made transportation of goods and people difficult, especially during winter months. Additionally, the challenging terrain of the Yukon River and surrounding mountains complicated access to gold-rich areas, impacting the influx of prospectors and the overall success of mining operations.
