Through the Shadow of Mt. Shasta, Union Pacific’s Valley and Black Butte Subdivisions DVD Mt. Shasta dwarfs everything in sight including the iron horses that have traversed its flanks for the past 130 years. This highway paved with steel continues to be a vital link between the Pacific Northwest and California. This DVD is a continuation of “The Shasta Route” returning to one of the favorite locations to view today’s Union Pacific in action. There is nothing like the show of modern high-powered diesels tackling a 2.2% mountain grade on a hot summer afternoon or racing through a frozen desert on a chilly winter morning. This is truly a stunning picture of trains traveling through the shadow of Mt. Shasta. 2 hours and 35 minutes of fabulous running.
