Discovery Canadian Original Series Premieres:

MUD MOUNTAIN HAULERS – Season 2

Mondays at 10 p.m. ET, beginning Oct. 31

In the new season of MUD MOUNTAIN HAULERS, brothers Craig and Brent Lebeau, third-generation loggers hoping for a successful logging season, and brothers Shane and Chad Glover, second-generation loggers based in the Kootenay region of B.C., along with their father Gary Glover, battle treacherous terrain, unpredictable weather, and complex machinery to get their logs to the mill.

In the season premiere “Let’s Get This Party Started,” Craig LeBeau and his crew set up camp in a remote part of the Shuswap Highlands, on the steepest, baddest block any of them has ever seen: Gollen. Things start out well, until bad weather and a stuck truck derail the entire operation. Meanwhile, Brent’s clearing a snowmobile trail for a local ski resort but, with so many jobs on the go, a mechanical oversight and impending snowfall may cost him the entire job.

MUD MOUNTAIN HAULERS is produced by Great Pacific Media.

THE MIGHTIEST – Series Premiere

Wednesdays at 8 p.m. ET, beginning Nov. 23

THE MIGHTIEST takes to the field to witness mega machines take on all-new mighty missions, giving viewers an all-access pass to every aspect of the vessel and the people around it as it embarks on a new and dangerous journey.

In the series premiere “Launch Day,” host Teddy Wilson is aboard the U.S. Navy’s newest and largest aircraft carrier USS Gerald R. Ford to document final training and tensions rising as the crew prepares for its long awaited first mission. The episode also looks at the massive Airbus A-380’s first landing into a major North American hub, the re-launch of a flying telescope after being grounded for months, and final touches on a cruise ship three times bigger than the Titanic.

LAST OF THE GIANTS – Season 2

Thursdays at 9 p.m. ET, beginning Nov. 24

After their action-packed adventures in North America and the Amazon, Cyril and the team are back with more high-adrenaline missions in Argentina, Nicaragua and the Marquesas Islands in the South Pacific.

In Argentina, searching for swamp-dwelling, deadly stingray, Cyril and the team venture into dangerous, uncharted rivers. Trekking through Nicaragua, the team skillfully evade deadly predators as they seek out the prehistoric giant Tarpon and the Goliath Grouper. Finally, journeying to the most remote islands in the South Pacific, Cyril leads a scuba dive through swarms of sharks and moray eels to find a giant trevally, an ocean predator capable of explosive attacks and even snatching birds from the sky.

LAST OF THE GIANTS is produced by Untamed Productions.

AFTER THE STORM – Two-Part Special Event

Thursday, Dec. 15 and 22 at 10 p.m. ET

In November 2021 an unprecedented storm slams into the Pacific Northwest, pummeling the region with a month’s worth of rain in just 48 hours. As rivers break their banks and landslides erupt from the coastal mountains,15,000 people flee their homes via crumbling highways and collapsing bridges. Many of those homes – and the land they sit on – are soon swept away.

AFTER THE STORM follows the events firsthand with the people who fought through this historic flood – from the first signs of trouble brewing over the ocean through the days of impact, with experts explaining the forces behind the disaster. In the aftermath engineers and towns race to rebuild vital infrastructure and roads connecting the coast to the rest of the country. Even when the trucks and trains are rolling again, the ongoing question is about the future: how to build back better in the face of more unpredictable weather – and more unforgiving storms to come.

Part 1 – “A River In The Sky” – Thursday, Dec. 15 at 10 p.m. ET

When the storm of the century hits the west coast, smashing rainfall records, no one is fully prepared. As the storm takes hold, landslides batter highways, trapping hundreds of drivers. Chelsey Hughes is heading home from a weekend getaway when a wall of debris slams into her car, throwing her into a river of mud and into a fight for survival. In the nearby Sumas region, community heroes like Gary Baars jump into action when rising water overwhelms the system of dikes and pumps that protects their land. Local farmers mount daring rescues of stranded workers and drowning livestock. As defenses collapse, one group of locals works through the night to save the pump station – their community’s last safeguard. In the storm’s aftermath workers race to rebuild dikes and reconnect important roads. Beyond the rush to fix what’s broken, experts explore new ways to manage life in vulnerable flood plains and adapt to the intensifying forces of nature.

Part 2 – “Hell or High Water” – Thursday, Dec. 22 at 10 p.m. ET

On the heels of the summer heat dome, which sparked catastrophic wildfires across southern B.C., November’s atmospheric river brings record-breaking rainfall. In the province’s desert-like interior, firefighter Dylan Bullock is still recovering from severe burns that he suffered in the wildfires. When parched mountains can’t absorb the rainfall, it pours into the rivers and into the city of Merritt. As floodwater submerges the nearby wastewater treatment plant, 7000 residents must evacuate – just as collapsing highways and bridges cut off escape routes. In small, isolated communities the raging Nicola River devours land and houses, stranding locals and triggering dramatic rescues. In the weeks that follow the storm, crews work tirelessly to fix the water plant and improvise repairs to let traffic and supplies start flowing, and engineers analyze what other countries are doing to mitigate flood damage and build more resilient infrastructure.
