#Regram #RG james_balog: Blackfoot Glacier, seen in a high alpine cirque below a sunrise-kissed Jackson Peak, is the second largest glacier in #GlacierNationalPark. However, like many of its siblings, it's one that stands to disappear by the end of the century. Indeed, the national park may one day need a new name. As the nationalparkservice celebrates its 100th birthday, it's important to not only look at these beloved parks' history, but also their future and what we can do to protect them. #NPS100 #climatechange #Anthropocene
