Location:

Airborne at 39,000 feet over Mt Robson, highest point in the Canadian Rocky Mountains (NE British Columbia)

Details:

As I flew past this brownish cloud of what looked to me like volcanic ash, I remembered that Alaska's Mt Redoubt was upstream from my location. Thanks to the SpaceWeather.com published SO2 animation, I was able to confirm my sighting. Volcanic ash has a certain look which can be rather rusty from certain angles with the sun low in the sky.
