There are more of these photos at the photographer's website, https://www.christianaslund.com/glacier-retreat , though no description. I found one at https://www.whitehouse.senate.gov/news/speeches/time-to-wake-up-melting-glaciers-and-the-warming-arctic.

According to it, Åslund dug out old photos and went to photograph the same places in 2003. I wonder how these places look today, in 2018?
