The Black Tusk is a very special mountain in Garibaldi Provincial Park, British Columbia, Canada. It looks like a giant, dark tooth pointing towards the sky. People who speak the St'at'imcets (Lillooet) language call it Q̓elqámtensa ti Skenknápa. In the Sḵwx̱wú7mesh (Squamish) language, it's known as T'ákt'akmúten tl'a Ín7inyáx̱a7en. This mountain is actually what's left of an ancient stratovolcano, which is a tall, cone-shaped volcano.
It stands 2,319 m (7,608 ft) high above the sea. You can see its sharp top from far away, especially from the Sea-to-Sky Highway near Whistler. The Black Tusk is one of the most famous mountains in the Garibaldi Ranges. It's part of a group of volcanoes called the Garibaldi Volcanic Belt.

Indigenous Stories and Names
For the Squamish people and the Lil'wat Nation, The Black Tusk is a very important place. It marks a traditional border between their lands. The Squamish name, T'ákt'akmúten tl'a Ín7inyáx̱a7en, means "Landing Place of the Thunderbird." The Thunderbird is a powerful, supernatural bird in their stories.
People say the mountain's jagged shape and dark color come from the Thunderbird's lightning. This story is also told about Mount Cayley, another volcano nearby. These stories connect the mountain deeply to the culture and history of the Indigenous peoples.
How The Black Tusk Was Formed
The Black Tusk is what remains of an extinct stratovolcano. This volcano was active about 1.3 to 1.1 million years ago. Imagine a huge, cone-shaped mountain that erupted long, long ago. Over time, glaciers and weather wore away the softer parts of the volcano.
About 170,000 years ago, new volcanic activity pushed up a lava dome at the summit. This dome created the hard, black rock spire we see today. Experts believe The Black Tusk was once a "conduit" or pipe for lava inside a volcano made of loose cinder. The soft cinder has eroded away, leaving only the tough lava core. This exposed lava rock is crumbly and black, which gives the mountain its name.
Volcanoes and Earth's Plates
The Black Tusk is part of a chain of volcanoes. This chain stretches from southwestern British Columbia all the way to northern California. These volcanoes formed because of how Earth's giant plates move. The Juan de Fuca Plate, Gorda Plate, and Explorer Plate are slowly sliding underneath the North American Plate. This process is called subduction. When one plate slides under another, it can cause volcanoes to form on the upper plate. This area where the plates meet is known as the Cascadia subduction zone.
Glaciers and Erosion
Today, The Black Tusk has two large glaciers. These glaciers sit in big, bowl-shaped hollows called cirques on the mountain's sides. They start high up, around 2,100 m (6,890 ft), and flow downwards. The glaciers are often covered with rocks and debris. This happens because the mountain's rock is quite crumbly and breaks apart easily. Glaciers also help shape the mountain by slowly carving away at its sides.
Exploring The Black Tusk
Many people enjoy hiking and scrambling on the lower parts of The Black Tusk. Scrambling means climbing over rocks using both your hands and feet. Most hikers start from the Taylor Meadows campground, which is near Garibaldi Lake. There's also another path from the north, passing by Helm Lake.
Reaching the Summit
Getting to the very top of The Black Tusk is a challenging adventure. The highest point, or true summit, is very difficult to reach. It involves climbing a short, exposed rock "chimney" to get to the south summit. The true summit is just a little higher, but it's across a dangerous drop. Only experienced climbers attempt this part. It requires special gear and skills, like using ropes to go down (a rappel) into a gap, then climbing up loose, crumbling rock. There's also a unique rock formation nearby called the "Bishop's Mitre," which is said to be extremely hard to climb.
