The creation of the train routes through the Cascade Mountains proved a monumental challenge. The conflict arose between the engineering capabilities of man and the treacherous topography and inclement weather of the region. The nine miles of track connecting the towns of Stevens Pass, Wellington and Scenic, Washington ultimately proved a failure for the Great Northern Railway. The Iron Goat Trail that retraces the former routing is a popular hiking destination. The trailhead is easily accessible by car. The well-maintained path leads you through traces of two ghost towns that were obliterated by avalanche. In the last decade of the 19th century, railroads were the primary mode of transportation for transcontinental passenger travel and freight. Previously isolated and inaccessible portions of the country became connected. Geographical impediments were merely obstacles to overcome. As profits swelled, ambitious and bold routings were designed and realized. During the 1890s, construction innovations enabled greater travel and more direct routes. These projects, employing tunneling and snow sheds, began lining the mountainous stretches immediately past Stevens Pass on the route to the Everett and Seattle stations. Immigrant laborers cleared the hillsides of mammoth trees. They drilled and blasted rock to create a flat grade. Camps were required for the hundreds of workers to maintain the tracks and keep them operational during the winter snows. Snowdrifts on the mountains often piled as high as 25 feet on either side of the tracks, creating artificial canyons and muffling warning noises. Snow slides often trapped and delayed trains for long periods of time until snowplows and large crews could manually shovel the paths.
