Berg Lake Aurora
This shot is looking South towards the North Face of Mt Robson over a very still Berg Lake. It was an amazingly clear night with the Milky Way rising and no sign of the moon so I walked down from our camp to the lake to take some astrophotography. We then had an aurora fire up so I turned around to take some shots North and watched the Aurora come and go for about 30 min. After the main aurora had faded, I went back to take a few more shots looking south over the lake to Robson as the Milky Way had lined up with the low point in the range. We then experienced the aurora related phenomena of ‘Steve’ accompanied by a ‘Picket Fence’ below it. Given we were looking South from a latitude of 53’ North this just makes it all the more incredible. ‘Steve’ was formally scientifically investigated in 2017 and determined to be caused by a 25 km wide ribbon of hot gasses at an altitude of 300 km, temperature of 3000 °C and flowing at a speed of 6 km/s (compared to 10 m/s outside the ribbon). The ‘Picket Fence’ below was slowly cycling to the right of frame. Berg Lake sits at an altitude of 1,646 m (5,400 ft). The North Face of Mt Robson rises 2,308m (7,572ft) out of the lake to a total height of 3,954 m (12,972 ft) and is the highest peak in the Canadian Rockies.
