One of the most distinguishable mountains in BC is the Black Tusk. Visible from many different heights in Whistler and the Garibaldi region, it is often talked about and almost always identified aloud when viewed in any form; people can’t help themselves from calling out “Black Tusk!” when they see it in pictures or from afar. Aside from its distinct and fascinating appearance, the Black Tusk has quite an interesting geological history.
In the last two million years volcanoes and glaciers have added dramatic scenery to the landscape of Whistler and the surrounding area. The topography of BC has been continually modified by glacial and steam erosion and the eruption of volcanoes. The Black Tusk, a local volcano that erupted about 170,000 years ago, is a reminder of our volcanic past. The Black Tusk is a stratovolcano, meaning it is made up of many layers of hardened lava, tephra, pumice, and volcanic ash. Centuries of erosion have stripped away its outer cone of bombs and ash, leaving behind solidified lava of its central conduit that now forms its narrow summit spire.
The Black Tusk reaches 2,319 m (7,608 ft) above sea level. Alike to well-known mountains such as Cerro Torre in Patagonia, the Barbarine in Germany, and the Vajolet Towers in Italy, it is a pinnacle, giving it its sharp and unmistakable structure. Pinnacles are individual columns of rock, isolated from other rocks or groups of rocks, that form the shape of a vertical shaft or spire.
The mountain hosts two significant glaciers that start from approximately 2,100 m (6,890 ft) and flow northward to below 1,800 m (5,906 ft). Both glaciers are heavily covered in debris due to the crumbling nature of the Black Tusk’s rock.
To the Squamish people, the Black Tusk is known as t’ak’t’ak mu’yin tl’a in7in’a’xe7en, meaning “Landing Place of the Thunderbird,” while for the L’íl’wat, the mountain is called Q’elqámtensa ti Skenknápa, meaning “Place where the Thunder Rests.” It is said to be named after the supernatural bird Thunderbird. The story goes that the jagged shape and black colouring of the Black Tusk is due to the Thunderbird’s lightning, or as another account goes, by the Thunderbird’s talons that crashed into the peak.
