Glacier National Park Quietly Removes Its ‘Gone by 2020’ Signs
Almost everywhere, the Park’s specific claims of impending glacier disappearance have been replaced with more nuanced messaging indicating that everyone agrees that the glaciers are melting. Some signs indicate that glacial melt is “accelerating.”
A common trick used by the National Park Service at GNP is to display old black-and-white photos of glaciers from bygone years (say, “1922”) next to photos of the same glaciers taken in more recent years showing the glaciers much diminished (say, “2006”). Anyone familiar with glaciers in the northern Rockies knows that glaciers tend to grow for nine months each winter and melt for three months each summer. Thus, such photo displays without precise calendar dates may be highly deceptive.
