These two trails were not the only ways to get to the gold fields near Dawson City, but they were the fastest and, thus, the most popular.
You may have seen an iconic photograph of the "Golden Steps" on the Chilkoot Trail, an endless line of fully-laden men trudging up a snowy, steep slope (the photo is in the description of Book #6). For many, that photo encapsulates the Gold Rush and the extreme effort of the men. What the image does not show is that most made that climb up to forty times! This repetition continued all along the trail. The magnitude of the stampeders’ efforts cannot be overstated. These men endured colossal hardships under the harshest conditions imaginable.
The White Pass Trail may have been worse. Thousands of pack animals died on its frigid pathways, causing it to be called the "Dead Horse Trail". With those unfortunate animals died many stampeders dreams.
I'm currently working on a second map; a regional map showing an area from Seattle, WA in the south to Dawson City, Yukon in the north. I will include that map in the book.
