Elevation change of Logan Pass in Glacier National Park 1977-2018

My parents visited Glacier National Park when they were dating in 1977, and my dad took a picture of the Continental Divide sign in Logan Pass. This past summer, they went back, and he took another picture of the same sign. In the intervening 41 years, the elevation listed on the sign decreased by 8 meters. Is there an explanation for this change?
