Flying over Garibaldi Provincial Park

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."

Learning to Fly

I wanted to do something special for Kathryn's birthday this year, so I bought her a flying lesson with Sea to Sky Air, out of the Squamish Valley. The airport in Brackendale is little more than an airstrip, helipad, assortment of fuel tanks, but the area around it is stunningly pretty and well worth the trip.

Our flight was onboard a small Cesna. Made of fiberglass and aluminum, this little four-seater (which the fish eye makes look bigger than it was) was light enough that our captain could pull it out and position it by hand. We had a very informative orientation session, walking around the entire craft and discussing how all of its pieces fit together and work before getting inside.

Covid continues to make everything a little more complicated, but since there were only 3 of us onboard, we were able to mask up and put Kathryn in charge. The plane has two sets of sticks with the rest of the controls in the middle, so she was able to try her hand at everything and could feel how the plane responded to the takeoff and landing (which she was part of but not in charge of)

Strangely enough, on the ground these planes are steered entirely with foot pedals which brake on the left or right to turn the craft, and the sticks are only used during flight.

Some of Kathryn's sea captain experience with currents and navigation was directly applicable to flight. While air is clearly a different medium than water, the fundamentals are similar and some technical controls, such as trim tabs, are comparable in nature between water and aircraft.

We were quickly in the air and soaring over the highway on our way to Garibaldi Park.
