This shot was taken on the same day as the iceberg lake photo. We stayed at a park campground and did not have an internet access (or even cellular signal). We had no clue that there was a strong aurora activity on July 6th (Kp index = 4). What I noticed was some weird faint glowing near the horizon toward Northeast. I was 100% sure that it was not any light pollution because there is no city nearby Glacier National Park to create light pollution. We pulled out at a bridge near Many Glacier hotel, just 1 mi before the trailhead to Iceberg Lake starting from Swiftcurrent Motor Inn.
It turned out to be a rare type of aurora, so called "pillars". This was my first time seeing them. It was a good to see them and let us feel awake to hike 4.8 mi to Iceberg lake.
