White Pass & Yukon, a narrow gauge railroad, was built in 1898 during the Klondike Gold Rush. This railroad, an integral part of mining, is now an International Historic Civil Engineering Landmark. The $10 million project employed thousands of men and used 450 tons of explosives, blasting through rugged mountain terrain. Today, the White Pass train travels from Skagway, Alaska to Bennett, British Columbia and carries over 35,000 visitors a season. The first forty miles of track are used in this popular shore excursion, but initially, this railway 'built with gold' covered 110 miles. The train track rises 3000 feet in 20 miles, with steep grades of almost 4% and moves through tunnels, over trestles and extremely high bridges. The sights along this 40 mile stretch are dramatic, and the train ride, breathtaking.
