I worked in Glacier National Park during the summer of 2015. This photo was taken on one of the most epic hikes I've ever done. A couple friends and I hiked to Iceberg Lake, climbed up the Ptarmigan Wall to Iceberg Notch (where this photo was taken), hiked to Ahern Pass, climbed Ahern Peak, hiked all the way around to Granite Park Chalet, then down Swiftcurrent Pass. In this photo, you can see the icebergs floating in Iceberg Lake. When compared with past photos, a significant reduction in snow and ice is very apparent, showing the effects climate change has caused over time.
