July 2017 — Grain Elevator in Thunder Bay, Canada.

July 2017 — The remains of the Saskatchewan Pool B complex in Thunder Bay, Ontario, stand as a testament to the city’s industrial and maritime heritage. Once part of one of the largest grain handling networks on the Great Lakes, these structures were built in the early 20th century to serve the growing wheat trade flowing from the Canadian Prairies to Atlantic markets. Operations here slowed by the 1980s as newer, more efficient elevators replaced them. Today, the site lies silent along the waterfront, its silos and offices weathered by decades of Lake Superior winds.

July 2017 — A rusted steel door and staircase, now surrounded by dense summer growth, mark one of the remaining entrances to the Saskatchewan Pool B grain elevator in Thunder Bay, Ontario. Completed in 1928, this concrete complex was once among the largest cooperative elevators on the Lakehead, operated by the Saskatchewan Wheat Pool to handle prairie grain for export through the Great Lakes. After the decline of Canada’s centralized grain trade, the elevator was shuttered and abandoned, leaving its reinforced concrete and steel framework to slowly merge with the encroaching forest.

July 2017 — Overgrown foliage surrounds the rusting stairway of the former Saskatchewan Pool B grain elevator in Thunder Bay, Ontario. Built in 1928 as part of the cooperative grain-handling network operated by the Saskatchewan Wheat Pool, the facility once stored and shipped millions of bushels of prairie wheat through the Lake Superior port. After decades of service under the Canadian Wheat Board era, the elevator was decommissioned and left to decay, its concrete silos and steel infrastructure now reclaimed by vegetation and time along the industrial waterfront.

July 2017 — The rusting conveyor systems and storage bins of the former Great West Lumber Sawmill stand as remnants of Thunder Bay’s once-thriving forest industry. Established near the Lake Superior waterfront in the early 20th century, the mill was part of a vast network that processed and shipped lumber across North America. Its maze of steel ducts and conveyors once carried sawdust, chips, and milled timber, feeding the region’s economic boom. Today, the overgrown machinery reflects a post-industrial landscape—silent evidence of a city that helped fuel Canada’s forestry trade for generations.

July 2017 — This steel swing bridge in Thunder Bay, Ontario, carries the Canadian Pacific Railway line across the Kaministiquia River near the city’s grain terminals.

Cast in iron more than a century ago, the cover remains a tangible remnant of early municipal engineering in northwestern Ontario.

July 2017 — The rocky shoreline at Taconite Harbor, Minnesota, once served as a vital shipping point for the state’s iron mining industry. Built in the early 1950s by the Erie Mining Company, the harbor was designed to handle massive shipments of processed taconite pellets from the Mesabi Iron Range, transported by a private 74-mile rail line to the Lake Superior coast. The harbor’s docks, loading equipment, and nearby company housing formed a self-contained industrial community that thrived for decades. The surrounding area was developed during a period of postwar expansion when Minnesota’s natural resources fueled North American manufacturing. Taconite Harbor operated until the early 2000s, when global shifts in steel production led to its closure. What remains today—crumbling concrete piers, rusted transmission towers, and wind-swept rock formations—speaks to both the resilience of the landscape and the region’s deep connection to the rise and fall of heavy industry along the North Shore.
