After the the flight lesson orientation, Captain Dave lead us on an hour long tour of his happy place, Garibaldi Provincial Park. The literal jewel of this park is Garibaldi Lake, which is fed by mountain runoff and stunningly azure, due to suspended particles in the meltwater known as "glacial flour."
This massive body of water is 1,500m above sea level with depths of up to 250m and held back by a lava dam known as "The Barrier." Captain Dave explained that, should there ever be an earthquake of sufficient magnitude, there is a good chance the natural dam will rupture and the lake will spill into the valley below.
Equally stunning, Table Mountain was a humbling testament to the passage of time and a reminder of the awesome power of the glaciers that once covered North America. Much like Siwash Rock or Devil's Tower, Table Mountain is the igneous funnel of an extinct volcano left behind after the softer sedimentary rock around it wore away.
The top is naturally so flat because its formative eruption took place when the entire area was covered in ice so thick that not even a volcano could impact it. The ice above stopped liquid rock and then ground it flat.
Towering at a height of 2,678 meters, the peak of Mount Garibaldi is an amazing sight from the air. The Sentinel and Sphinx glaciers feed the lake below as they recede a little more each year. Despite global warming, these ice fields remain massive, which fissures hundreds of feet deep and jagged rocks poking through into the clouds at the top, evoking the Antarctica flight from "At the Mountains of Madness."
