"In the spring of 2019 I broke the story that National Park Service had quietly removed signs in GNP which predicted the glaciers would all be gone by 2020...
The average date of first freeze in East Glacier is September 13, and this is generally when the glaciers stop melting and begin growing again.
It is only then that comparisons can be made with prior years.
- However, official U.S. government websites show images of GNP’s glaciers with captions giving just the years; not the calendar dates. By juxtapositioning a photo from, say, “1911,” showing a huge glacier, next to a photo of the same glacier—much diminished—from, say, “2009,” these government websites seek to depict the glaciers as steadily melting. See here, here, and here.
- But anyone who lives in glacier country knows that glaciers generally grow each year for 9 months and melt for 3 months. A picture taken in July will show a glacier much larger than a picture of the same glacier taken in September.
