Cascade Locks and Canal - Paperback

A stretch of tumbling white water five miles long, the Cascades of the Columbia River were the single greatest barrier to inland river trade and travel in the Pacific Northwest. One solution, the Cascade Locks and Canal, took nearly 18 painstaking years to construct. From 1878 to 1896, hundreds of laborers blasted, chipped, and hauled over 800,000 cubic yards of rock and debris from the riverbed, carved and laid masonry, and welded steel to create the locks. After their completion, thousands of trips, millions of dollars in freight, and hundreds of thousands of passengers made their way through the locks. Made redundant in 1938 by the completion of the Bonneville Dam, the remnants of the structure are still visible today in Cascade Locks, Oregon.
