What visitors are actually seeing

U-shaped valleys, cirques, sharp ridges, lakes, moraines, and waterfalls tell the glacial story throughout the park. Remaining glaciers occupy high mountain settings and may require distant viewpoints or substantial hiking.

Why the experience is time-sensitive

U.S. Geological Survey measurements and repeat photographs make the loss visible, while current modeling projects continued retreat and eventual disappearance. Seeing the remaining ice and understanding the changes already underway makes a visit even more historically meaningful.
